Where is chlorophyll found?

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

How does chlorophyll work?

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 ), these chlorophyll pigments can be separated into chlorophyll a and chlorophyll b .

Why do chlorophylls appear green?

Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll a and b.

What is the most important pigment in photosynthesis?

Chlorophyll-ais the most important photosensitive pigment for the photosynthesisprocess. It resides in the membranes of thylakoid disks of the chloroplasts. It is assisted by accessory pigmentsin the antenna arraysthat absorb the light and direct the energy to chlorophyll-a pigment complexes. The accessory pigments broaden the wavelength range of the light absorption, but it is chlorophyll-a that accomplishes the final step of handing off energetic electrons in two photosystems called Photosystem Iand Photosystem II. These energetic electrons accomplish the step of photophosphorylationto produce the vital energy currency, ATP, but in the non-cyclic electron transportwhich uses both photosystems, they also provide the energy for the synthesis of glucose and other carbohydrates.
