Trees are fascinating and complex plants that are grown worldwide. Many people learn from a young age how to identify various species, but few understand the basic anatomy of a tree. While you probably know they’re made up of roots, a trunk and a crown, here’s a close look at each of these parts. The roots Tree roots form an intricate system that branches out in every direction beneath the ground. They’re usually shallow and widespread, sometimes stretching for over 50 kilometres. Tree roots provide structural support and stability. They also collect water, oxygen and minerals from the soil. The root system is fuelled by the sugar that’s generated from the tree’s leaves. In turn, the roots collect nutrients that feed the rest of the tree. The trunk Tree trunks extend up toward the sky. This allows the plant to grow tall enough for its leaves to come into contact with plenty of sunlight. Tree trunks are solid structures that have wood at their core. If you look at a cross-section of a trunk, you’ll see many different bands and rings. These markings are made of densely packed cells that comprise the heartwood, sapwood and bark. Each of these parts is responsible for strengthening and supporting the tree. The inner layer transports nutrients up into the branches and leaves, while the outer layer protects the tree from heat, fire, frost, insects and disease. The crown The crown is the top part of the tree. It includes branches, twigs, leaves and sometimes flowers and fruits. A tree branch is an arm-like structure that extends from the trunk and culminates in vascular appendages known as leaves. Leaves collect sunlight and water to feed the tree. They do this using a process known as photosynthesis, which converts sunlight into energy. This process is responsible for taking in carbon dioxide and releasing oxygen into the air. This is one of the reasons that trees are so important for the environment. They’re also extremely resilient and efficient. They can survive all year by hibernating in the winter. When there’s less sunlight, they drop their leaves to help conserve energy.
