Dear Studemt
Photosynthesis in plants is a very important chapter which contains many topics which need to be done for NEET:
History of Photosynthesis- especially Engelmann experiment
Chloroplast
Photosynthetic Pigments
Processes related to photosynthesis. Asorption and action spectrum,
Two pigment system- PSI and PS II
Cyclic Photophosphorylation, Noncyclic Photophosphorylation- Z scheme, Chemiosmosis
Calvin Cycle
C4 cycle
CAM Plants
The concept of limiting factors Factors Affecting Photosynthesis, C2 Cycle Or Glycolate Pathway
It would be difficult to explain whole chapter in this answer. You may schedule a session with experts for understanding this chapter in particular.
