Question

Why do desert plants take up carbon dioxide at night? explain in detail.

Answer 1

Deserts have a very hot climate and receive very less rainfall annually. Like other green plants, desert plants also prepare food by photosynthesis, during which small pores (stomata) on a plant's leaves and stems open to absorb CO₂ from the air. However, each time a plant opens its pores, some water is lost. If this happens frequently during daytime, high temperatures will cause the water to evaporate quickly. To prevent this, the desert plants do not open their pores for carbon dioxide until the sun goes down.
