CoachA tree is a big plant whose stem is made of wood. The tree’s woody stem is called the trunk; it divides into branches, which carry the leaves.
Examples
Example 3.7 (The chestnut tree)
The chestnut tree in the yard has the same plan as the daisy, but bigger and harder: roots under the ground, a trunk instead of a soft stem, branches with thousands of leaves, and in spring, flowers. The daisy lives one year; the chestnut can live longer than a hundred.
