HOW PLANTS DEFEND THEMSELVES
- Plants also develop special organs to defend themselves.
- They need to protect themselves from animals - dryness - cold. In order to defend themselves from animals, the leaves and the stem of some plants are transformed into thorns.
- Then it is not possible for the animals to eat the plant.
- Plants which grow in very dry areas transform their leaves and stem into water containers, and they can live without rain for a very long time. For example, a cactus plant.
- Plants defend themselves from the cold by developing very thin pointed leaves, like needles, covered with a thick film which protects them from the cold.
- Plants which are not able to develop leaves like needles lose their leaves during the winter and "hibernate."
