How do plants carry out photosynthesis under extremely hot and dry conditions?

Answer 1

The plants that grow in hot and dry conditions are called xerophytic plants. Water conservation is key to their survival. So, they have innovated a new protocol of photosynthesis called CAM pathway, i.e., Crassulacean acid metabolism. In this pathway, such plants keep their stomata open in night to take up CO2 while their stomata remain closed during the day in order to avoid transpiration. In the daytime, they synthesize glucose from CO2.

Answer 2

Plants have adapted to hot and dry conditions through mechanisms such as CAM photosynthesis or succulence. In CAM photosynthesis, plants open their stomata at night to minimize water loss during the day. Succulent plants store water in their leaves or stems to withstand drought conditions. This helps plants minimize water loss and continue with photosynthesis even in hot and dry environments.
