HOW PLANTS DEFEND THEMSELVES

1. Plants also develop special organs to defend themselves.
2. 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.
3. Then it is not possible for the animals to eat the plant.
4. 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.
5. 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.
6. Plants which are not able to develop leaves like needles lose their leaves during the winter and "hibernate."
