Unlike animals, plants do not eat; they make their own food through a process called "photosynthesis". During this process, the leaves use SUNLIGHT, carbon dioxide and water to make food. Plants need sunlight to survive.

When it rains, DESERT PLANTS such as cacti and other succulent (juicy) plants take up as much water as possible and store it in their leaves and stems which will provide the water they need during the dry months. Their waxy leaves and stems also slow down water loss through transpiration.

Some DESERT PLANTS have a short life cycle. When the rains come, these plants sprout quickly, flower and die. Their seeds lie dormant in the soil, until the next rain enables them to germinate and bloom.
