Photosynthesis is the process used by plants, algae and certain bacteria to turn sunlight, carbon dioxide (CO2) and water into food (sugars) and oxygen.
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. They both follow very similar principles, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
Oxygenic photosynthesis is a non-cyclic photosynthetic electron chain where the initial electron donor is water and, as a consequence, molecular oxygen is liberated as a byproduct. ... Oxygenic photosynthesis was responsible for the transformation of the Earth's primitive anoxygenic atmosphere to one with molecular oxygen.Cyanobacteria perform photosynthesis using water as an electron donor in a similar manner to plants. This results in the production of oxygen and is known as oxygenic photosynthesis.
Anoxygenic photosynthesis is a bacterial photosynthesis that occurs under anaerobic conditions, using the photosynthetic electron transport chain in a non–cyclic mode and reduced inorganic electron donors, such as hydrogen sulfide, hydrogen, or ferrous ion, as electron donors. example:-green sulfur bacteria (GSB), red and green filamentous phototrophs (FAPs e.g. Chloroflexi), purple bacteria, acidobacteria, and heliobacteria.
