Introduction Trees are all around us, in forests, gardens, and parks. There are many different trees, and they give us many things. Where do you see trees? What do we get from trees? Discover! Now read and discover more about trees!
Chapter 1 What Is a Tree? A tree is a tall plant. It has leaves, branches, a trunk, and roots. A tree makes its food with light from the sun. It grows tall so it can get lots of light. Discover! Some coast redwood trees are 110 meters tall! A tree grows every day. Look at this old tree trunk. How old is it? Count the rings. Every ring is one year.
Chapter 2 Parts of a Tree What do the different parts of a tree do? Leaves grow on branches. They make food for the tree. To make food they use water, air, and light from the sun. Roots take water from the ground. The trunk takes food down the tree from the leaves, and it takes water up the tree from the roots. Bark is the wood on the outside of the trunk. It protects the trunk.
Chapter 3 Flowers and Seeds Some trees have big flowers. Some trees have very little flowers. Flowers make pollen. The wind blows pollen from one flower to other flowers. Insects take pollen to other flowers, too. Then the tree can grow seeds. Seeds grow inside fruit. The fruit protects the seeds. The fruit falls from the tree. Then the seeds go into the ground. New trees grow from the seeds!
