Chlorophyll's job in a plant is to absorb light—usually sunlight. ... 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.

Role of Chlorophyll in Photosynthesis
Plants and other photosynthetic organisms use chlorophyll to absorb light (usually solar energy) and convert it into chemical energy. ... Chlorophyll absorbs light and uses resonance energy transfer to energize reaction centers in photosystem I and photosystem II.
What is the role of chlorophyll in the process of photosynthesis Class 7?
Chlorophyll can absorb the energy from sunlight. The sunlight energy absorbed by chlorophyll is used to combine carbon dioxide and water in the green leaves to produce food. Chlorophyll absorbs light energy from the sun and supplies this energy to the leaves to enable them to carry out photosynthesis for making food.
What is the function of chlorophylls A and B?
Chlorophyll A and B are the two major pigments, involved in photosynthesis. Chlorophyll A is the primary pigment of photosynthesis, trapping the light energy and emitting highenergy electrons into the two photosystems P680 and P700. Chlorophyll B is the accessory pigment, passing the trapped energy into chlorophyll A.
What do reaction center chlorophylls do?
The function of the reaction center chlorophyll is to use the energy absorbed by and transferred to it from the other chlorophyll pigments in the photosystems to undergo a charge separation, a specific redox reaction in which the chlorophyll donates an electron into a series of molecular intermediates called an ...
What is special about the chlorophylls in the reaction center?
The reaction center contains a pair of chlorophyll a molecules with a special property. Those two chlorophylls can undergo oxidation upon excitation; they can actually give up an electron in a process called a photoact. It is at this step in the reaction center, that light energy is converted into an excited electron.
What are the roles of chloroplast and chlorophyll in photosynthesis?
The role of chlorophyll in photosynthesis is vital. Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.
What is chlorophyll Class 7 short answer?
Chlorophyll is a pigment present in all green plants and a few other organisms. It is required for photosynthesis, which is the process by which light energy is converted into chemical energy. The chlorophyll pigment is responsible for the green colouration in plants.
What is the role of chlorophyll in photosynthesis * 1 point a imparting color to leaves B store food C reflect the sunlight d trap the sunlight?
Chlorophyll is a green pigment that gives the green color to the leaves. Chlorophyll plays a major role in photosynthesis as it is used for absorbing the sun light. The sunlight is stored in the chlorophyll that is utilized as a source of energy for undergoing the the process of photosynthesis.
Why do different bacteria have different chlorophylls?
These types of chlorophyll and bacteriochlorophyll differ in structure, and those differences affect the specific wavelength of light that each can absorb, which allows several different species of microbes together to collect the full spectrum of light, each absorbing a different range of wavelengths.
What is the main function of the carotenoids?
Carotenoids have been shown to have two major functions in photosynthesis. They act as photoprotective agents, preventing the harmful photodynamic reaction, and as accessory light-harvesting pigments, extending the spectral range over which light drives photosynthesis.
What is the role of carotenoids in photosynthesis?
Carotenoids are essential in oxygenic photosynthesis: they stabilize the pigment–protein complexes, are active in harvesting sunlight and in photoprotection. In plants, they are present as carotenes and their oxygenated derivatives, xanthophylls.
What are the roles of ATP and Nadph in photosynthesis?
ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases dioxygen (O2) molecule.
What is the role of reaction Centre of photosystem in photosynthesis?
Transforming light energy into charge separation
A variety in light-harvesting complexes exist across the photosynthetic species. Green plants and algae have two different types of reaction centers that are part of larger supercomplexes known as P700 in Photosystem I and P680 in Photosystem II.
What is the function of DPIP in this experiment?
The function of the DPIP in this experiment is to act as the electron acceptor, replacing the usual NADP found in plants. When the light shines on the active chloroplasts, the electrons are excited, which causes them to jump to a higher energy level thus reducing the DPIP.
Where does charge separation occur in photosynthesis?
In photosynthetic reaction centers from purple bacteria (PbRC) and the water-oxidizing enzyme, photosystem II (PSII), charge separation occurs along one of the two symmetrical electron-transfer branches.
Is the site of light reaction of photosynthesis?
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs.
What takes place in the reaction center of chloroplasts?
In chloroplasts, light-harvesting complexes consist of a web of chlorophyll molecules linked together and held tightly in the thylakoid membrane by a matrix of proteins. ... 2) Charge separation- energy is transferred to the reaction center; an excited electron is transferred to an acceptor molecule.
