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 diffeent

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

Text Solution

Verified by Experts

The correct Answer is:
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.
