Question
Water 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
-
Both processes cannot happen simultaneously
Solution
A.
Both processes can happen together because the diffusion coefficient of water and CO2 is different
Diffusion of water vaour and C02 are an independent process. Their diffusion depends on the difference in their ppartial pressure in the atmosphere as well as inside the leaves.
