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.
