Question

Why do desert plants open their stomata at night?

Answer 1

Hey mate here is ur answer.

Most plants require the stomata to be open during daytime. The air spaces in the leaf are saturated with water vapour, which exits the leaf through the stomata; this is known as transpiration. Therefore, plants cannot gain carbon dioxide without simultaneously losing water vapour.

Answer 2

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 time.
