Question

Desert vegetation has short thorny shrubs and plants with waxy leaves or no leaves. Give reason

Answer 1

Desert vegetation has short thorny shrubs and plants with waxy leaves or no leaves. This is because such areas have high temperatures with very little or no rainfall.
The desert vegetarian has adapted to such conditions and so contains, short thorny shrubs that can grow with very little moisture. The plants contain waxy or no leaves to save on the water evaporation through the leaves.
