Which of the following plants does not show photorespiration

A. Pea

B. Wheat

C. Rice

D. Maize

Answer: Option D

Solution(By Examveda Team)

Photorespiration is the process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.
C4 plants do not show photorespiration as these plants maintain a high concentration of carbon dioxide in the bundle sheath cells and the absence of grana ensures no release of oxygen due to photolysis. Thus, photorespiration is absent in such plants. And maize is one of the C4 plants.
