how desert plants perform photosynthesis if their stomata remain closed during the day?
Asked by yaradhna875 | 27 Oct, 2020, 10:25: PM
answered-by-expert Expert 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.

water is in the form of H2O, and from the equation it is clear that concentration of hydrogen is more in water, since, thier are 2 atoms of hydrogen in a single molecule, my main question was, why water is not flammable? as liquid version of hydrogen is used as fuel in space shuttle, which is combined with oxygen, and in water, both are present. Please reply. I am having this doubt from long time.
