Question

Explain in short how desert plant makes their food

Answer 1

Desert plants work hard to make use of what's available. They use the sun's energy to convert carbon dioxide (CO2) and water (H2O) into sugar, a process called photosynthesis. During this process, stomata on a plant's leaves and stems open to absorb carbon dioxide from the air and in return release oxygen. Each time a plant opens its pores, some water escapes. This is called transpiration.

Replacing this lost water is not easy with so little annual moisture, and if the water cannot be replaced, the desert plants will die. So desert plants have acquired special adaptations that help them reduce water loss.
