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
1 One process occurs during day time, and the other at night
2 Both processes cannot happen simultaneously
3 Both processes can happen together because the diffusion coefficient of water and \(\mathrm{CO}_{2}\) is different
4 The above processes happen only during night time
Explanation:
In plants, both photosynthesis and transpiration occur at the same time. Water vapour and \(\mathrm{CO}_{2}\) both move out and inside the cell as the diffusion coefficient of the two is different and each moves along its concentration gradient.

Select the incorrect statement from the following?
1 \({{\rm{C}}_{\rm{4}}}\) plants are twice as efficient as \({{\rm{C}}_{\rm{3}}}\) plants in terms of photosynthesis
2 The humidity of rainforests is largely due to the vast cycling of water
3 Photosynthesis is limited by available water which can be swiftly depleted by transpiration
4 \({{\rm{C}}_{\rm{3}}}\) plants loses only half as much water as a \({{\rm{C}}_{\rm{4}}}\) plants for the same amount of \(\mathrm{CO}_{2}\) fixed
Explanation:
A \({{\rm{C}}_{\rm{4}}}\) plant loses only half as much water as a \({{\rm{C}}_{\rm{3}}}\) plant for the same amount of \(\mathrm{CO}_{2}\) fixed.

Which of the following does not promote opening of stomata?
1 Blue light
2 Cytokinin
3 Red light
4 High carbon dioxide inside leaf
Explanation:
High carbon dioxide concentration does not cause opening of stomata while it causes the closing of stomata. So, the correct answer is High carbon dioxide concentration
