Question

Specify how c4 photosynthetic pathway increases co2 concentration in bundle sheath cells of sugarcane.

Answer 1

Answer:

The C4 pathway acts as a mechanism to build up high concentrations of carbon dioxide in the chloroplasts of the bundle sheath cells. The resulting higher level of internal carbon dioxide in these chloroplasts serves to increase the ratio of carboxylation to oxygenation, thus minimizing photorespiration.
