Question

How do desert plants prepare their own food?

Answer 1

The desert plants also prepare their food with the help of photosynthesis.

In this, CO2 from air and water from soil is needed to react with sunlight to form sugar and starch.

Here, photosynthesis differs from plant to plant, the desert plants need very less water to survive and prepare their food.

Thus, when CO2 combines with H2O, oxygen is given out as a by-product.

Answer 2

Explanation:

Desert plants do not synthesise food during the day due to the process of transpiration. So they may lose water through the stomata..

... In order to overcome this problem, the desert plants absorb CO2 during night and store it to photosynthesize later during daytime in the presence of sunlight...
