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.

第二章树的各个部分一棵树的不同部分有什么作用? 叶子长在树枝上。它们为树做食物。 他们利用水、空气和太阳光来制造食物。 根从地下吸收水分。 树干从叶子上吸收食物，从根部吸收水分。 树皮是树干外面的木头。 它保护树干。

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!

第三章花和种子有些树开着大花。 有些树的花很少。 花产生花粉。风把花粉从一朵花吹到另一朵花上。 昆虫也会把花粉带到其他花上。 这样树就可以长出种子了。 种子生长在果实里面。果实保护种子。 果子从树上掉下来。 然后把种子埋到地里。 新的树木从种子中长出来!
