1. Any of a wide variety of perennial plants typically having a single woody stem, and usually branches and leaves. Many species of both gymnosperms (notably the conifers) and angiosperms grow in the form of trees. The ancient forests of the Devonian, Mississippian, and Pennsylvanian periods of the Paleozoic Era were dominated by trees belonging to groups of seedless plants such as the lycophytes. The strength and height of trees are made possible by the supportive conductive tissue known as vascular tissue.

Etymology

Explanation

A tree is a large plant with a trunk, branches, and leaves. If you have an apple tree in your backyard, you'll have apples in the fall — and a nice shady place to sit in the summer. The thick, woody trunk is actually the stem of a tree, and its ability to grow so much taller than other plants evolved partly as a way for trees to absorb more sunlight. Trees do a lot for humans, including providing oxygen, giving us places to climb, producing fruit, shading us, and providing lumber and fuel. As a verb, tree means "chase into a tree," the way your dog might tree the neighbor's cat.
