Photosynthesis Pigments

Photosynthesis Pigments

	Photosynthesis Pigments - There are three main classes of photosynthesis pigments, chlorophylls (Chl) (including bacteriochlorophylls, BChl), carotenoids and phycobilins (phycobiliproteins: PBPs). All species capable of carrying out photosynthesis contain one or more types of chlorophyll or bacteriochlorophyll and carotenoids.
Phycobilins are found only in the red algae (Rhodophyta: eukaryotes) and the blue green bacteria (Cyanobacteria: prokaryotes). All phototrophic bacteria, except the Cyanobacteria, contain bacteriochlorophylls and carotenoids.
