【题目】Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they have no teeth or claws. But plants can still 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) havesharp spines () that discourage grass-eating animals. Holly leaves on lower branches have more prickles thanleaves on upper branches. 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 grasses may contain a sandy material,so eating such grasses wears down the animal's 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(毛虫) bites a tobacco leaf, the leaf produces a chemical smell.

Many plants depend on both physical and chemical defense. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous water(毒液).Only one experience with this kind of plant will teach an animal to stay away from it in the future.
