Oxygenic and Anoxygenic Photosynthesis

Oxygenic and Anoxygenic Photosynthesis

	Oxygenic and Anoxygenic Photosynthesis - In the Cyanobacteria and Pro chlorophyta photosynthesis is oxygenic, i.e. there is evolution of oxygen. There are two linked photosystems involved in photosynthesis. The electron donor is H₂O, and oxygen is the ultimate product of oxidation. They are, therefore, aerobic phototrophs.
The photosynthetic apparatus of the Cyanobacteria is remarkably similar in structure and function to the eukaryote chloroplast. Their light harvesting pigments, Chl a and phycobiliproteins, are homologous to those of the chloroplast of Rhodophyta (red algae).
