新一轮中考复习备考周期正式开始， There are several characteristics which distinguish plants from animals. Generally speaking, plants are able to manufacture their own food, by using substances in the environment through the process which is known as photosynthesis. They can grow very well if they have enough sunshine, rainfall and fertilizer. In contrast, all animals, including man, get their food either directly from the plants or indirectly by eating animals which feed on plants or other animals. Animals, therefore, need a wide range of food than plants. Plants are stationary. They do not have the power to move. Animals, on the other hand, can usually move about. Consequently, plants appear to be less sensitive then animals although they respond in some ways to light, heat, physical contact and other stimuli. Plants are usually green. Animals, however are very diverse in external appearance. They may appear in any color you can think of (责任编辑：admin) |
