Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases. This function is performed by stomata. Water is absorbed by roots from the soil, whether from irrigation or rain.

What are the 4 raw materials and end products of photosynthesis?
Plants perform photosynthesis in the presence of sunlight, water and carbon dioxide to produce food and oxygen. Sunlight, water and carbon dioxide are the raw materials; food and oxygen are the products of photosynthesis.
What are the two materials of photosynthesis?
Green Tree Leaves – The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll. Photograph courtesy of Shutterstock Most life on Earth depends on photosynthesis,The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
The process During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Chlorophyll Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.
- During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.
- Light-dependent reactions vs.
- Light-independent reactions While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light- dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH,
The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light- independent reaction. During this stage, energy from the ATP and NADPH molecules is used to assemble carbohydrate molecules, like glucose, from carbon dioxide.
C3 and C4 photosynthesis Not all forms of photosynthesis are created equal, however. There are different types of photosynthesis, including C3 photosynthesis and C4 photosynthesis. C3 photosynthesis is used by the majority of plants. It involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose.
C4 photosynthesis, on the other hand, produces a four-carbon intermediate compound, which splits into carbon dioxide and a three-carbon compound during the Calvin Cycle. A benefit of C4 photosynthesis is that by producing higher levels of carbon, it allows plants to thrive in environments without much light or water.

What raw material is not used in photosynthesis?
Hint: Photosynthesis is a process of making food by green plants in the presence of sunlight. It is the process by which light energy gets converted into chemical energy. Plants require certain raw materials to carry out photosynthesis to produce food in the form of carbohydrates (i.e., glucose).
- Complete step by step answer: Option (A) is correct.
- Oxygen is not essential for the process of photosynthesis because oxygen is released in this process when plants utilize the raw materials i.e., carbon dioxide and water to produce sugars (glucose).
- Hence, it is not essential to carry out the process of photosynthesis.
Option (B) is incorrect. Carbon dioxide is an essential component of photosynthesis in plants to make food. It is the carbon dioxide molecule that reacts with water to form glucose and oxygen. Option (C) is incorrect. Sunlight is one of the important requirements to carry out photosynthesis by plants.
- As photosynthesis is carried out in two phases i.e., light and dark phase so, in the light phase, energy from the sunlight is used to split the water molecule which releases two electrons that are used to form NADPH and ATP molecules.
- Option (D) is incorrect.
- The whole process of photosynthesis takes place in the chloroplasts of a plant that contains a green-colored pigment called chlorophyll.
It is the chlorophyll molecule that is meant for absorbing the light rays coming from the sun. Hence, it is essential for photosynthesis. Hence, the correct option is (A) Note: Plants containing chlorophyll use carbon dioxide, water, and sunlight to produce food (in the form of glucose) and release oxygen with the formation of ATP and NADPH. As oxygen is produced by plants, so, it is not an essential component to start the process of photosynthesis.
What are the 3 sources of materials for photosynthesis?
What is Photosynthesis When you get hungry, you grab a snack from your fridge or pantry. But what can plants do when they get hungry? You are probably aware that plants need sunlight, water, and a home (like soil) to grow, but where do they get their food? They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source.
Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2). CREDIT: mapichai/Shutterstock.com Just like you, plants need to take in gases in order to live.
- Animals take in gases through a process called respiration.
- During the respiration process, animals inhale all of the gases in the atmosphere, but the only gas that is retained and not immediately exhaled is oxygen.
- Plants, however, take in and use carbon dioxide gas for photosynthesis.
- Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots.
Plants also require water to make their food. Depending on the environment, a plant’s access to water will vary. For example, desert plants, like a cactus, have less available water than a lilypad in a pond, but every photosynthetic organism has some sort of adaptation, or special structure, designed to collect water.
- For most plants, roots are responsible for absorbing water.
- The last requirement for photosynthesis is an important one because it provides the energy to make sugar.
- How does a plant take carbon dioxide and water molecules and make a food molecule? The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.
After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair. The oxygen that is produced is released from the same tiny holes through which the carbon dioxide entered. Even the oxygen that is released serves another purpose.
Other organisms, such as animals, use oxygen to aid in their survival. If we were to write a formula for photosynthesis, it would look like this: 6CO 2 + 6H 2 O + Light energy → C 6 H 12 O 6 (sugar) + 6O 2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
Imagine a pea plant. If that pea plant is forming new pods, it requires a large amount of sugar energy to grow larger. This is similar to how you eat food to grow taller and stronger. But rather than going to the store and buying groceries, the pea plant will use sunlight to obtain the energy to build sugar.
- When the pea pods are fully grown, the plant may no longer need as much sugar and will store it in its cells.
- A hungry rabbit comes along and decides to eat some of the plant, which provides the energy that allows the rabbit to hop back to its home.
- Where did the rabbit’s energy come from? Consider the process of photosynthesis.
With the help of carbon dioxide and water, the pea pod used the energy from sunlight to construct the sugar molecules. When the rabbit ate the pea pod, it indirectly received energy from sunlight, which was stored in the sugar molecules in the plant. We can thank photosynthesis for bread! Wheat grains, like the ones pictured, are grown in huge fields. When they are harvested, they are ground into a powder that we might recognize as flour. CREDIT: Elena Schweitzer/Shutterstock.com Humans, other animals, fungi, and some microorganisms cannot make food in their own bodies like autotrophs, but they still rely on photosynthesis.
- Through the transfer of energy from the Sun to plants, plants build sugars that humans consume to drive our daily activities.
- Even when we eat things like chicken or fish, we are transferring energy from the Sun into our bodies because, at some point, one organism consumed a photosynthetic organism (e.g., the fish ate algae).
So the next time you grab a snack to replenish your energy, thank the Sun for it! This is an excerpt from the Structure and Function unit of our curriculum product line, Science and Technology Concepts TM (STC). Please visit our publisher, to learn more.
What is the 4 step of photosynthesis?
The different phases of photosynthesis are: Absorption of light, Transfer Of electrons, Production Of ATP, and Carbon Fixation.
What are 10 raw materials?
Understanding Raw Materials – Raw materials are used in a multitude of products and can take many different forms. Raw materials are the input goods or inventory that a company needs to manufacture its products. For example, the steel used to manufacture vehicles would be a raw material for an automobile manufacturer.
- For manufacturing companies, raw materials inventory requires detailed budgeting and a special framework for accounting on the balance sheet and income statement,
- Raw materials are often related to natural resources.
- For this reason, manufacturing companies may be at the disposal of mother nature regarding the availability to secure raw materials.
In the same light, manufacturing companies may not want to directly invest in extracting the raw materials. For example, consider how a company that relies on oil or plastics often does not own the drilling rig that extracts the raw materials from the group.
What are the raw materials and end products of chloroplast?

The products of photosynthesis are glucose and oxygen.
What are end products of photosynthesis?
Glucose and oxygen are the final products of photosynthesis.
What is the main product of photosynthesis?
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O 2 ) and a form of sugar called glucose (C 6 H 12 O 6 ).
Is oxygen raw material for photosynthesis?
Oxygen and water are the raw materials for photosynthesis.
Is sunlight not a raw material for photosynthesis?
Hint: Photosynthesis is the process utilized by the plants through which conversion of light energy into chemical energy takes place. It is an endothermic reaction. The chemical energy generated in the reaction is utilized to meet the metabolic activities and cellular respiration of the plant.
- The photosynthesis process is primarily maintaining the oxygen level of earth’s atmosphere.
- Besides, it is responsible for supplying most energy, which is indispensable for life on the planet earth.
- Complete answer Raw materials for photosynthesis: Carbon dioxide and water are the main raw materials for the process of photosynthesis.
Besides, light energy and chlorophyll are also raw materials for photosynthesis. Sunlight is the energy source, which is essential for photosynthesis to take place. If any of the raw materials is missing, photosynthesis will not take place. The missing raw material will become a limiting factor.
Sources of raw materials for photosynthesis Through stomata, plants absorb carbon dioxide from the atmosphere. The process for absorption is gaseous exchange. They get water from the soil through roots and transport it to leaves. Water is provided by rain or irrigation. Chlorophyll and other green parts in the plants trap the sunlight.
Sun provides the light energy needed for the reaction. Note: The leaf is a solar collector, made up of photosynthetic cells. The raw materials enter the cells of leaves through plant cells known as xylem, photosynthesis takes place in the presence of sunlight and the end products, sugar and oxygen are produced.
What is not a raw material?
Metals that are naturally-occurring trace constituents or contaminants of other substances are not considered to be raw materials. Cullet and material that is recovered from a furnace control device for recycling into the glass formulation are not considered to be raw materials for the purposes of this subpart.
What color is chlorophyll?
Chlorophyll – The green pigment in leaves is chlorophyll, which absorbs red and blue light from sunlight. Therefore, the light the leaves reflect is diminished in red and blue and appears green. The molecules of chlorophyll are large (C55H70MgN4O6). They are not soluble in the aqueous solution that fills plant cells.
Instead, they are attached to the membranes of disc-like structures, called chloroplasts, inside the cells. Chloroplasts are the site of photosynthesis, the process in which light energy is converted to chemical energy. In chloroplasts, the light absorbed by chlorophyll supplies the energy used by plants to transform carbon dioxide and water into oxygen and carbohydrates, which have a general formula of Cx(H2O)y.
In this endothermic transformation, the energy of the light absorbed by chlorophyll is converted into chemical energy stored in carbohydrates (sugars and starches). This chemical energy drives the biochemical reactions that cause plants to grow, flower, and produce seed.
How do plants get carbon dioxide?
How do plants produce oxygen? Plants, just like people, need food to survive. Plants, however, can’t just run down to the shop and get the ingredients for a nice sandwich for their lunch! So, they have to make their own kind of food. Plants make their food in a process called photosynthesis.
- What a big word! It actually means “making things using light”, photo meaning light, and synthesis meaning “to make”.
- Plants need three main ingredients to make their food: water, carbon dioxide and sunlight.
- Plants take up the water that they need from the soil through their roots.
- Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.
Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air. Take a look at the picture below to see this system in action.
This leftover oxygen is really important because humans and other animals need this oxygen to live which we breathe in from the air. When we breathe out, we release carbon dioxide into the air which is then used by the plants to make their food and the cycle starts all over again. This system is called the oxygen cycle.
Hopefully you can see that plants and the process that makes oxygen is important for the plant, but also for humans and other animals as well! What do you think would happen to the amount of oxygen available if we were to chop down all the trees? Do you think this would be good for humans and other animals? If you would like to see this process in action, here is a little experiment you can try at home! Carefully take a green leaf from a plant and put it in a glass of water, make sure the leaf is fully submerged in the water.
Why is oxygen needed for photosynthesis?

- Oxygen (O 2 ) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH—the energy source and reducing power for plant metabolism.
- The majority of this chemical energy is used to drive photosynthetic carbon metabolism, which consists of ribulose-1,5-bisphosphate carboxylation (photosynthetic carbon reduction cycle) and oxygenation (photosynthetic carbon oxidation cycle); with a combined electron requirement = J A,
Four electrons are required for every O 2 evolved so that gross O 2 production (GOP) is related to linear electron transport (J) according to J /4. When linear electron transport is used only to drive CO 2 fixation, the consumption of O 2 and the release of CO 2 by photosynthetic carbon oxidation and mitochondrial respiration is such that net O 2 production (NOP) is equal to net CO 2 assimilation ( A net ; provided the respiratory quotient is 1, but see Tcherkez et al., 2017 ).
Additionally, electrons can be used for alternative noncyclic electron transport (ANCET), including, for example, the photoreduction of O 2 itself forming reactive oxygen species (Mehler-peroxidase reactions or “water-water cycle”; Asada, 1999 ), chloroplastic anabolism (e.g. lipids; Stumpf et al., 1963 ), the reduction of oxaloacetate to malate (which is exported to the mitochondria; Scheibe, 2004 ), and nitrogen assimilation ( Bloom et al., 1989 ).
ANCET has been hypothesized both as a way to regulate ATP/NADPH ratio to meet the changing energy demands of cellular metabolism and as a mechanism to prevent photodamage through utilizing excess reductant when the photon flux density exceeds the energy requirement of CO 2 fixation (e.g.
- Under high irradiance, cold temperatures, water stress closing stomata; e.g.
- Badger, 1985 ; Ort and Baker, 2002 ; Robinson, 1988 ).
- Importantly, there is no formal evidence for how electron flows interact, particularly under fluctuating light conditions ( Morales et al., 2018 ).
- As ANCET allows for greater rates of linear electron transport to be sustained, total electron transport ( J t ) will be greater than J A,
Conversely, the effect on O 2 uptake will be dependent on the metabolic pathway involved. For example, in the Mehler-peroxidase reactions, there is no net change in O 2 so that NOP will remain equal to A net, But in the reduction of nitrate, the ratio between N-linked O 2 production and O 2 consumption is highly dependent on the amino acid synthesized ( Noctor and Foyer, 1998 ).
In this case, NOP will not always equal A net because O 2 and CO 2 may not be balanced in metabolism ( Skillman, 2008 ). Consequently, concomitant measurements of CO 2 and O 2 fluxes are important to the understanding of how plants regulate the use of light energy, with different fates having very different metabolic outcomes.
The earliest measurements of O 2 evolution were unable to distinguish GOP from uptake of O 2 ( Hill, 1937 ). The mass spectrometry method established by Mehler and Brown (1952) solved this problem by employing O 2 isotope tracers to independently monitor fluxes of 16 O 2 and 18 O 2,
In this method, pure 18 O 2 was supplied to the gas headspace of a closed chamber, and the decline in 18 O 2 was attributed to O 2 uptake. O 2 evolved carries the same isotopic composition as the water from which it is generated; in this case, the dominant isotope in the water was 16 O ( Fig.1 ). The 18 O-labeling approach was further applied to leaf disks (e.g.
Tourneux and Peltier, 1995 ), whole excised leaves (e.g. Volk and Jackson, 1972 ), and entire plants ( Gerbaud and André, 1980 ), illuminating the fate of O 2 in vivo. Simple representation of the reactions that can be involved in gross O 2 production and uptake of a photosynthesizing cell, showing how labeled 18 O water results in the production of 18 O 2 in the approach developed by Gauthier et al. (2018), In the case of reactions within the peroxisome and mitochondria, this only represents net O 2 consumption, i.e.
there is both uptake and release occurring. PSII, Photosystem II; PSI, Photosystem I; Fd, Ferredoxin; M, Mehler reaction; PCR; photosynthetic carbon reduction; PCO, photosynthetic carbon oxidation; PGA, 3-phosphoglycerate; P-Glyc, phosphoglycolate; Glyox, glyoxylate; OAA, oxaloacetate; Mal, malate. The limitation of closed gas exchange systems is that measurements can only be undertaken for short periods of time (seconds to minutes) before the CO 2 concentration is depleted.
Consequently, CO 2 :O 2 is not constant, which changes the relative rates of carboxylation and oxygenation so that estimates of GOP and O 2 uptake will be inaccurate. This limitation was overcome in the mass spectrometry approach by replacing CO 2 consumed through periodic influx of CO 2 into the chamber, allowing for steady-state quantification and extending the ability to measure O 2 fluxes under a range of conditions and physiological states ( Canvin et al., 1980 ).
- At the same time, advances were being made in the use of chlorophyll fluorescence, which provides information on PSII quantum yield ( Baker, 2008 ).
- Genty et al.
- 1989) provided the empirical link between fluorescence and electron transport rate, replacing the need to directly measure O 2 evolution.
- Chlorophyll fluorescence is now one of the most popular techniques in plant physiology because of its ease of use and relatively low cost.
This has been aided by the capacity to multiplex fluorescence measurements with H 2 O and CO 2 gas exchange in portable, commercially available instruments, opening up the possibility of measuring plant function outside of the laboratory. Consequently, in vivo measurements of O 2 fluxes have substantially declined over the last 20 years.
- In this issue of Plant Physiology, Gauthier et al.
- 2018) remind us why it is so important to return our attention to O 2, providing us with a new, elegant open-path system to measure O 2 fluxes.
- Their method is a “reverse” isotopic approach, involving 18 O-labeling of leaf water rather than the air so that the isotopic composition of O 2 that is evolved during water splitting has a signature very different to that of ambient O 2 ( Fig.1 ).
The use of considerable 18 O enrichment is imperative since the contribution of NOP in a background of 21% O 2 is likely to be in the order of 0.05% (e.g.100 μmol mol −1 NOP/210,000 μmol mol −1 ambient O 2 ), making it difficult ordinarily to accurately detect a change in δ 18 O of O 2 associated with NOP in the air surrounding the leaf.
- The method remains highly technical, requiring the use of three high-precision instruments.
- The isotopic composition and concentration of CO 2 and H 2 O vapor are measured by laser spectroscopy, and the δ 18 O 2 and δO 2 /N 2 (to estimate O 2 concentration) by mass spectrometry.
- A custom-made chamber is also required to house the excised leaf and its 18 O-labeled water source, which helps to prevent leaks across the gaskets from around the petiole.
Importantly, the open gas exchange system improves the ability to achieve steady-state measurements, and labeling water versus the use of pure 18 O 2 gas solves the affordability issue, which has greatly limited the adoption of open systems. While chlorophyll fluorescence has become the popular option for measuring electron transport rate, it is not without assumptions.
For example, it is frequently assumed that leaves absorb 84% of incident photons and that 50% of these photons are absorbed by PSII; however, this may not always be the case ( Baker, 2008 ). This may lead to an overestimate of electron transport rate when computed from fluorescence compared with measurements of GOP.
Furthermore, accurate determination of J A is particularly relevant for the estimation of mesophyll conductance, which was one application highlighted by Gauthier et al. (2018), The Mehler-peroxidase reactions, which have been shown to range from 0% to 30% ( Driever and Baker, 2011 ), would lead to an overestimate of electron fluxes associated with the photosynthetic carbon reduction/oxygenation cycles in both methods.
- However, the advantage of the isotope labeling approach is that the contribution of the Mehler reaction to gross O 2 production can be quantified by coupling measurements of GOP with NOP (e.g.
- Furbank et al., 1982 ; see Fig.1 ).
- Now that we have a renewed ability to measure O 2 fluxes, these assumptions should not be ignored.
Besides understanding the trade-off between efficiency and photoprotection for improved agricultural production ( Murchie and Niyogi, 2011 ), the different electron fates have important implications for understanding global O 2 fluxes. Notably, O 2 uptake associated with photorespiration, mitochondrial respiration, and the Mehler-peroxidase reactions have different isotope fractionation factors ( Guy et al., 1993 ) so that the quantification of individual pathway fluxes is needed to constrain estimates of global primary production from δ 18 O information ( Welp et al., 2011 ).
What is photosynthesis for kids?
photosynthesis Photosynthesis is the process in which green use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
- Chlorophyll is a substance in all green plants, especially in the leaves.
- Plants take in water from the soil and carbon dioxide from the air.
- Photosynthesis starts when chlorophyll absorbs from sunlight.
- Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars.
The plants use some of the sugars and store the rest. The oxygen is released into the air. Photosynthesis is very important because almost all living things depend on plants for food. Photosynthesis is also important because of the oxygen it produces. Humans and other animals need to breathe in oxygen to survive.
Why are plants green?
Many-fruited thyme-moss – Chlorophyll is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet. Although microscopic in size, chloroplasts like these have a big role to play in the health of the planet. Photograph by Kristian Peters—Fabelfroh, licensed under CC BY-SA 3.0 Unported. Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll, A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
- There are many different types of pigments in nature, but chlorophyll is unique in its ability to enable plants to absorb the energy they need to build tissues.
- Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells.
- This is where photosynthesis takes place.
- Phytoplankton, the microscopic floating plants that form the basis of the entire marine food web, contain chlorophyll, which is why high phytoplankton concentrations can make water look green.
Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
- Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts.
- The process of photosynthesis produces oxygen, which is released by the plant into the air.
- Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light.
That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs. Animals that eat plants or other animals are called heterotrophs. Because food webs in every type of ecosystem, from terrestrial to marine, begin with photosynthesis, chlorophyll can be considered a foundation for all life on Earth.
Where is chlorophyll found?
What Cells and Organelles Are Involved in Photosynthesis? – Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. In electron micrographs, thylakoid membranes look like stacks of coins, although the compartments they form are connected like a maze of chambers.
The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4). Chlorophyll A is the major pigment used in photosynthesis, but there are several types of chlorophyll and numerous other pigments that respond to light, including red, brown, and blue pigments.
What are all end products of photosynthesis?
Glucose and oxygen are the final products of photosynthesis.
What are the final products of photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
What is photosynthesis and its end product?
It is the process by which plants use sunlight, water, and carbon dioxide to make sugar i.e., glucose.
What are the end products of photosynthesis needed for?
What Are the End Products of Photosynthesis? – Answer: Plants are autotrophs because they synthesize their own food by the process known as photosynthesis. Photosynthesis is a process in which plants use sunlight and water to form glucose and oxygen. It is not as easy as it seems.
There are many several steps combined into one single equation representing the process of photosynthesis.6CO 2 + 6H 2 O + light energy = C 6 H 12 O 6 + 6O 2 CO 2: carbon dioxide H 2 O: water C 6 H 12 O 6 : glucose O 2 : oxygen Reactants of Photosynthesis The plants take the exhaled carbon dioxide through the small opening in their leaves known as stomata.
Plants suck the water through their roots present in the surrounding soil. The water is carried up to the leaves through the xylem tissues. Initiation of Photosynthesis Plant cells have organelles called chloroplasts which are specialized for carrying out the process of photosynthesis using water, carbon dioxide, and sunlight.
- Their thylakoid membrane has a pigment called chlorophyll which has the ability to absorb the photons (light energy) from the sun.
- During these reactions, water is broken down into its constituent hydrogen and oxygen ions, and high energy molecules are produced.
- These molecules are NADPH and ATP.
- They are used in the formation of glucose.
Electrons and hydrogen ions are used to build NADPH. The hydrogen ion is used in the conversion of ADP to ATP. Products of Photosynthesis The oxygen ion combines to form oxygen gas. The oxygen leaves the plant leaves through stomata. The light dependent reactions along with the energy power molecules (ATP and NADPH) break down carbon dioxide molecules into a form that is used to build glucose.
