Desert Plants
  • Many plants are found in the desert. They usually
    grow close to the ground.
  • These plants have special parts that help them
    save water.
  • The special parts are thick stem, shallow and
    wide roots, and thick skin covered with spines
    instead of leaves.

Desert Animals
  • There are many animals in the desert.
  • They can survive by eating other animals or by
    eating plants that store water.
  • To protect them from the hot sun, they stay in
    the shade or in their shelter.
  • Animals may build their shelters inside plants.
  • Some animals sleep during the day and are active
    at night.
  • Some animals have hard shells to protect them
    from losing much water.
  • More animals live in hot deserts than in cold
    deserts.
