<unk>  (also<unk>   is a term used for several closely related green pigments found in cyanobacteria and the<unk> oroplasts of algae and plants. Its name is derived from the Greek words χλωρός,<unk> oros ("green") and φύλλον, phyllon ("leaf").<unk>  is an extremely important biomolecule, critical in photosynthesis, which allows plants to absorb energy from light.<unk>  absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of<unk> -containing tissues.<unk>  was first isolated by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817.
