The main components of a tree are four parts. From bottom to top, they are roots, trunk, branches, and leaves. Tree roots are the vegetative organs of trees and can absorb water and nutrients. Above the roots is the trunk part, which can play a supporting role. Branches are branches above the trunk, branches that extend upward. Leaves are leaves that grow on branches and can synthesize nutrients.

1. Root

1. Roots

Roots are the vegetative organs of trees and are a very important part. They are usually underground and supply the growth of trees by absorbing water and nutrients from the soil, and they can also be stored. Nutrients, when there is no moisture in the soil, can still rely on stored nutrient supplies to grow.

2. Trunk

Above the root It is the trunk part. The outermost layer is bark. This is the most superficial part of the trunk. It can protect the trunk from external invasion and prevent diseases from invading the tree body. It can play a very good protective role. Underneath the bark is the phloem, which transports sugars. The third layer is a very critical part, it is the cambium layer. This layer is relatively thin, but it is the center of gravity of growth. The next layer is sapwood, which transports water from the roots to the tree. This layer is lighter in color. The fifth layer is heartwood, and most of the trunk is heartwood.

3. Branches

The branches are The branches above the trunk are branches that extend upward. They gradually become thicker as they grow, and can determine the general shape of the tree.

Four. Leaves

Leaves are The leaves growing on the branches absorb sunlight through the leaves, and then synthesize nutrients to supply the growth of the tree.
