Multiple Choice QuestionsWater vapour comes out from the plant leaf through stomatal opening. through the same stomatal opening. carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statements using the following options
Both processes can happen together because the diffusion coefficient of water and CO2 is different
The above processes happen only during night time
One process occurs during day time and other at night
One process occurs during day time and other at night
A.
Both processes can happen together because the diffusion coefficient of water and CO2 is different
