Question

What is the special feature of the leaves of C4 plants?

Answer 1

The special feature of the leaves of a C4 plants is that it has mesophyll and bundle sheath cells which photosynthesis is divided in each of them. Also, chloroplast is present in both mesophyll and bundle sheath cells.

Answer 2

The photosynthesis processes of C4 plants are divided between mesophyll and bundle sheath cells. Two steps of C4 photosynthesis that occur in the mesophyll cells are the light-dependent reactions and a preliminary fixation of CO2 into a molecule called malate.



CO2 is released from malate in the bundle sheath cells, where it is fixed again by Rubisco and the Calvin-Benson cycle. The PEP is then recycled back to the mesophyll cells, and the carbohydrate products of photosynthesis are distributed through the plant.
