A tree is a tall plant with a trunk and branches made of wood. Trees can live for many years. The oldest tree ever discovered is approximately 5,000 years old. The four main parts of a tree are the roots, the trunk, the branches, and the leaves. The roots of a tree are usually under the ground. One case for which this is not true are the roots of the mangrove tree which are often under water. A single tree has many roots. The roots carry food and water from the ground through the trunk and branches to the leaves of the tree.
