A look at how cacti are able to survive and grow in the harsh, dry desert environment. The spines on a cactus help to protect it from humans and animals. Its roots are spread out to collect water when it does rain and it stores water in its body for future use.
Plants have many adaptations to cope with the lack of water. Some desert plants, such as the barrel cactus, have expandable stems for storing water. Other plants have adaptations that reduce water loss from their leaves, the part of a plant through which most of the water is lost. Still others have a waxy coating on the leaves, or have small leaves, that reduce the surface area exposed to the drying elements. In many cases, desert plants have no leaves at all.
