Question

State the adaptations in C4 plants that allows it to be more productive than C3 plants

Answer 1

Answer:

C4 plants are more efficient than C3 due to their high rate of photosynthesis and reduced rate of photorespiration. The main enzyme of carbon fixation (Calvin cycle) is RuBisCO, i.e. ribulose bisphosphate carboxylase oxygenase. It has an affinity for both CO2 and O2.

Answer 2

In addition to above answer C4 plants also have Kranz anatomy. They have 2 types of cells i.e. bundle sheath cells and mesophyll cells .
In C4 plants water loss is 1/4times of C3 thats why in these plants photosynthesis is more and the wastefull process photorespiration is minimum or absent.
