C4 plants are the plants that form C4 compound during photosynthesis called oxaloacetate. The C4 plants are much more efficient than the C3 plants as they show the adaptive feature to avoid a harmful process in plants called photorespiration.
The process of photorespiration uses excess ATP and NADPH and also decreases the amount of sugar which occurs when the RUBP binds oxygen instead of Carbon dioxide in the Calvin cycle.
So the plants try to maintain the concentration of carbon dioxide during the Calvin cycle. This is done by the formation of oxaloacetate, separation of the site of the light-dependent phase which takes place in the mesophyll cell and the light-independent phase in the bundle sheath cells.
C4 plant are capable to deal with photorespiration
Explanation:
C4 are more efficient than the C3 plants because the C4 have a mechanism to deal with the photorespiration. C4 combat photorespiration by fixing the intial carbon dioxide between mesophyll and bundle-sheath cells (in space)and calcin cycle. The light dependent process and the calvin cycle are separate in C4 plants. Also C4 plants can adapt easily to even hot sunny environment
