Components of a tree

1. Root

The roots are the nutritional organs of trees and a very important part. They are usually located underground and absorb water and nutrients from the soil to supply the growth of trees. They can also store nutrients. When there is no water in the soil, they can still rely on stored nutrients to grow.

2. Trunk

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

3. Branches

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

4. Leaves

Leaves are the leaves that grow on tree branches. They absorb sunlight and then synthesize nutrients to supply the growth of trees.
