Question

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 one of following options : (A) Both processes can happen together because the diffusion coefficient of water and CO2 is different (B) The above processes happen only during night time. (C) One process occurs during day time, and the other at night (D) Both processes cannot happen simultaneously

Transpirational loss of water occurs through stomata gaseous exchange also occurs through stomata in terrestrial plants. Simultaneously as both are the process of simple diffusion occurs in order of diffusion pressure gradient or diffusion coefficient.

Q. 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 one of following options :

Both processes can happen together because the diffusion coefficient of water and $C O_{2}$ is different

The above processes happen only during night time.

One process occurs during day time, and the other at night

Both processes cannot happen simultaneously

Transpirational loss of water occurs through stomata & gaseous exchange also occurs through stomata in terrestrial plants. Simultaneously as both are the process of simple diffusion occurs in order of diffusion pressure gradient or diffusion coefficient.
