Question

Desert plants lose less water through transpiration

Answer 1

desert plants lose less water through transpiration because, in desert there is a lack of water and the plants also store water in their fleshy leaves and stems.

Answer 2

To Survive in Desert, the terrestrial plants need to decrease the Transpiration level to avoid much of water loss. So these plants have evolved to have smaller leaves so that there are fewer Stomata. On the other hand some plants have also evolved to convert their leaves into Thorns, such as Cactus.
