Question

Importance of such differences in cells of c3 and c4 plants

Answer 1

Photorespiration is a wasteful pathway that occurs when the Calvin cycle enzyme rubisco acts on oxygen rather than carbon dioxide.

The majority of plants are C3 plants, which have no special features to combat photorespiration.

C4 start subscript, 4, end subscript plants minimize photorespiration by separating initial CO2 fixation and the Calvin cycle in space, performing these steps in different cell types.
