Photosynthesis In Higher Plants of Class 11
Photosynthesis is the synthesis of carbohydrate from sunlight, water and CO2 by the green plants (autotrophic). It is an endergonic and anabolic process.
Bacteria shows anoxygenic photosynthesis as they do not use water and do not evolve oxygen. Cyanobacteria (blue green algae) evolved oxygen first time in evolution as they show oxygenic photosynthesis.
