Chlorophylls
Autotrophic organisms possess chlorophyll, in chloroplasts, to conduct photosynthesis. There are a few forms of chlorophyll described below, and can be assigned to evolutionary groups.
Chlorophyll a
Chlorophyll molecule that absorbs mostly violet-blue and orange-red light. This pigment is found in plants, algae, cyanobacteria, and prochlorophytes
Chlorophyll b
Chlorophyll molecule that absorbs mostly blue light. This pigment is found in green algae, land plants, and prochlorophytes
Chlorophyll c
Chlorophyll molecule that makes a golden or brownish color and is an accessory pigment. This pigment is found in SAR supergroup such as dinoflagellates, diatoms, and brown algae
Chlorophyll d
Chlorophyll molecule that absorbs far-red light, at 710 nm wavelength, which is still available in deep ocean settings. This pigment is found in red algae and cyanobacteria.
Chlorophyll f
Chlorophyll molecule that absorbs further in the red (infrared light) than other chlorophylls. In 2010, it was reported from stromatolites from Western Australia's Shark Bay.
