Plants

    Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot do so. Animals get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. Therefore animals and man need plants in order to live.

    There are two main types of plants: flowering plants and nonflowering plants.

    Flowering plants have root systems, leaves, flowers and fruits. Almost all the trees around us are flowering plants. Most plants do not grow from seeds. They grow from spores (孢子). Spores are very small. They are so small and light that they can float in the air. They are quite similar to seeds. When they fall on wet and shady (成荫的) place, they usually grow into new plants.
