Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Trunks, also called boles, are the stems of woody plants and the main structural element of trees. The woody part of the trunk consists of dead but structurally significant heartwood and living sapwood, which is used for nutrient storage and transport. Separating the wood from the bark is the cambium, from which trunks grow in diameter. Bark is divided between the living inner bark, which transports sugars, and the outer bark, which is a dead protective layer.
