Question

stostomata of desert plants remain closed during the day. Explain how and when they take up carbon dioxide to perform photosynthesis ​

Answer 1

Answer:

Such plants undergo CAM photosynthesis as they open up their stomata during night and take in CO2. Stomata remains close during the day time to prevent the loss of water by transpiration. They store the CO2 in their cells until the sun comes out and they can carry on with photosynthesis during the day

Answer 2

Answer:

In desert plants, the stomata is open during night. During night, desert plants absorb carbon dioxide and form an intermediate. Then during day time when the stomata is closed to prevent loss of water, they use this stored carbon dioxide to perform photosynthesis.
