阅读下面短文，简略回答问题。
Animals can move from place to place, but plants can't. When an animal is under attack, it can run away or fight back. Plants can't run away or fight back because they have no legs or claws. But plants can also protect themselves in both physical and chemical ways.
Some plants have their own ways to keep animals away. For example, the leaves of the hollies（冬青树）have sharp prickles（刺）that discourage animals. Holly leaves on lower places have more prickles than leaves on upper places. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak trees（橡树）, have thick and hard leaves that are difficult for animals to eat. Some plants may contain a rough material in their stems, so eating such leaves wears down the animals' teeth.
Many plants also have the chemical defense. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may protect themselves by increasing the production of these chemicals. When a worm bites a tobacco leaf, the leaf produces a chemical smell.
Many plants depend on both physical and chemical defense. A kind of plant in China, for instance, has prickly leaves, and each prickle has poisonous（有毒的）water. Only one experience with this kind of plant will teach the animal to stay away from it in the future.
