The process which makes major difference between C3 and C4 plants is ;
|
|
Calvin cycle
|
|
|
Photorespiration
|
|
|
Respiration
|
|
|
Glycolysis
|
Explanation:
Detailed explanation-1: -Hence, the correct answer is ‘Photorespiration’.
Detailed explanation-2: -Spatial separation of carbon dioxide fixation and RUBISCO activity in mesophyll and bundle sheath cells of C4 plants respectively avoids photorespiration by concentrating CO2 in bundle sheath cells to scale down the oxygenase activity of RUBISCO and increase the RUBISCO efficiency which is not the case in C3 plants.
