Structure of a Tree

The leaves, bark, and roots are the main structure of a tree.

The Leaves:
As we have learned from elementary school, the leaves convert carbon dioxide into oxygen to provide the tree with energy to grow and fight any diseases.

The Roots:
The roots are the means to take up water and minerals. They provide structural stability to the tree.

The Bark:
It is the outer protective covering of the tree trunks. Well, we have seen different form and structure of a bark.
