Class 11 Biology Chapter 13 Photosynthesis in Higher Plants: Important Topics

Photosynthesis in higher plants involves additional processes, but fundamentally it remains the same. It is a physicochemical process that uses sunlight for the synthesis of organic compounds. In this process, oxygen is released into the atmosphere.

Photosynthesis takes place in the chloroplast, found in the mesophyll cells of the leaves. There are 4 pigments involved in photosynthesis:

Chlorophyll a
Chlorophyll b
Xanthophylls
Carotenoids

Photophosphorylation

Photophosphorylation is the formation of ATP in the presence of sunlight. It is of two types:

Non-cyclic photophosphorylation
Cyclic photophosphorylation

Dark Reaction

This process takes place in the absence of light in the stroma of the chloroplasts.

The following cycles are involved in the process:

Calvin Cycle (C3 Cycle)
C4 Cycle (Hatch and Slack Pathway)
