What is the term for the main part of a tree from which everything grows?

The main part of a tree from which everything grows is referred to as the trunk. The trunk serves as the central support structure of the tree, connecting the roots to the branches and leaves. It is typically cylindrical and provides stability and strength, allowing the tree to reach upwards towards sunlight. The trunk also houses the vascular system that transports nutrients and water between the roots and the rest of the tree, contributing to its growth and overall health.

In contrast, the crown represents the upper part of the tree where the leaves and branches are located, while the roots are underground structures that anchor the tree and absorb water and nutrients from the soil. Branches extend from the trunk but are not considered the main part of the tree itself.
