tree trunk
Bark-covered timber pillar
The tree trunk is the main woody stem of a tree, rising from the roots and supporting the branches and crown.
It's the thick central column you see between ground and canopy: She carved her initials into the tree trunk.
The trunk contains layers—bark, cambium, sapwood, heartwood—that transport water and nutrients while providing structural support.
