Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets food by eating plants and animals, too. So animals and man need plants to live. This is why there are so many plants around us.

    There are two kinds of plants: flowering plants and non-flowering (无花的)plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruit. Non-flowering plants do not grow flowers. You cannot see many non-flowering plants around you.

    If we look carefully at the plants around us, we will find that there are many kinds of plants. Some plants are big and some are small. Most of them are green. We can live on the Earth because of the plants around us.
