Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statements using the following options.A. Both processes can happen together because the diffusion coefficient of water and `CO_(2)` is diffeentB. The above processes happen only during night timeC. One process occurs during day time and the other at nightD. Both processes cannot happen simultaneously

Answer» Correct Answer - A
Diffusion of water vapour and `CO_(2)` are independent process. Their diffusion depends on the difference in their partial pressure in the atmosphere as well as inside the leaves.
