Tree Pod Burial Tree Types, Learn the different layers of a tree and why each is important. All of the thousands of species of trees fall into two categories – deciduous trees and evergreen trees. In general, a plant is considered a tree if its height reaches more than 13 feet, lives for many years, and has a woody stem. Unlike shrubs, trees typically have a single trunk and can grow to significant heights. Most of these trees are common in North America, Europe, and other countries around the world. Parts like roots, trunk, branches, leaves, flowers, and fruits all work together to keep the tree healthy. They are found in different climates and regions, ranging from towering forest trees to fruit-bearing and ornamental varieties. Get a breakdown of how trees are classified and explore the definitions of various tree-related terms. Most plants classified as trees have a single self-supporting trunk containing woody tissues, and in most species the trunk produces secondary limbs, called branches.
