NEET2016BotanyTransport in PlantsActual
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 the following options:
Options
- ABoth processes cannot happen simultaneously
- BBoth processes can happen together because the diffusion coefficient of water and C O 2 is different
- CThe above processes happen only during night time
- DOne process occurs during day time, and the other at night
Correct answer
B. Both processes can happen together because the diffusion coefficient of water and C O 2 is different
Step-by-step solution
Water vapour comes out and C O 2 diffuses simultaneously through stomatal opening because the diffusion coefficient of water and C O 2 is different and it moves along its concentration gradient.
