Question

In xerophytic plants stomata is closed during day time. how do they take up carbon dioxide

Answer 1

Such plants undergo CAM photosynthesis as they open up theirstomata during night and take inCO2.Stomata remains close during theday time to prevent the loss of waterby transpiration. They store the CO2 in their cells until the sun comes out andthey can carry on with photosynthesis during the day time.

hope helps ☺️☺️
