Question

Why do desert plants take up carbondioxide at night?

Answer 1

Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO2).

Answer 2

IN SIMPLE LANGUAGE.
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 the 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.
