Question

How do the following help these plants to survive?

Answer 1

Desert plants have plenty of sunlight. But they receive very little water. When it does rain, they soak up as much water as they can. Their roots are often very close to the surface of the soil or sand. They are ready and waiting to catch any drop of water that falls.

Their next challenge is to hang onto the water. Desert plants have a thick, waxy surface. They have spikes instead of leaves. This stops a lot of water from being lost across their outside surface.
