Question

What is chlorophyll??
Very long answer…..

Answer 1

Answer:

Chlorophyll makes plants green. It's basically a group of green pigments used by organisms that convert sunlight into energy via photosynthesis. ... Without this energy, plants would be unable to initiate the process of photosynthesis, which converts water and carbon dioxide into starches that plants can use for food.

Answer 2

Answer:

Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants.[2] Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf").[3] Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.

Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light.[15]

Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.[16] In these complexes, chlorophyll serves three functions. The function of the vast majority of chlorophyll (up to several hundred molecules per photosystem) is to absorb light. Having done so, these same centers execute their second function: the transfer of that light energy by resonance energy transfer to a specific chlorophyll pair in the reaction center of the photosystems. This pair effects the final function of chlorophylls, charge separation, leading to biosynthesis. The two currently accepted photosystem units are photosystem II and photosystem I, which have their own distinct reaction centres, named P680 and P700, respectively. These centres are named after the wavelength (in nanometers) of their red-peak absorption maximum. The identity, function and spectral properties of the types of chlorophyll in each photosystem are distinct and determined by each other and the protein structure surrounding them. Once extracted from the protein into a solvent (such as acetone or methanol),[17][18][19] these chlorophyll pigments can be separated into chlorophyll a and chlorophyll b.
