Why do most desert plants have waxy skin?

Question 3 options:

To help the plant store or save water inside

Because it is hot in the desert

So animals won't eat the plant

To help the plant collect rain water

The correct answer is: To help the plant store or save water inside.

Desert plants often have a thick, waxy layer on their skin, known as a cuticle, which helps reduce water loss through evaporation. This adaptation allows the plant to conserve water and survive in the arid conditions of the desert.
