When people think of plants, they usually think of gardens, parks, or even jungles. One place that does not usually come to mind is the desert. However, some deserts contain many plants that are able to grow and survive under difficult conditions.
Deserts can reach temperatures of 50 degrees or more in the daytime and can also drop below 0 degrees at night. This is a huge temperature difference under which desert plants have to live. Besides the high and low temperatures, all deserts receive very little water in the form of rain; sometimes it doesn’t rain for months. So, how do desert plants get water when there is no rain?
There are three main ways plants survive in the desert. First, some desert plants grow without leaves. Others have developed special ways of storing whatever water they can find, such as growing a waxy leaf covering that helps keep water inside the leaf. These plants can survive for weeks or months on the water collected from just one rainfall.
A second way desert plants survive even in the most difficult conditions is by growing very long roots. These roots spread out and search for any water they can find. Once they find water, the roots suck up as much as they can and then hold it, only allowing the plant above the ground to have small amounts at a time.
The third way plants survive in the desert is by “sleeping”. Some plants can turn off almost all their processes and just remain inactive, almost as if dead, while they wait for rain. When the rain does come, they quickly drink up every drop they possibly can and burst back into activity.
