Question

Plants in the Sahara have long roots and small, leathery leaves.

Answer 1

Plants in the Sahara have long roots and small, leathery leaves. This is because the Sahara desert records very high temperature. Coupled with low precipitation and cloudless days, the rate of evaporation of water from the leaves of plants is very high. That is why plants in this region have small and leathery leaves to reduce transpiration. Moreover, the roots of the plants are long as they have to dig deep in order to access the limited groundwater resources.
