why desert plants take up oxygen at night ?
Answers
Answer:
Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out.

Answer:
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.
