There are thousands of tree species all over the world and all these trees share the same anatomical features. All trees have trunks, branches, intricate rooting systems and leaves that make up their core systems. If you are curious about the anatomy and importance of each part, reading this guide by Five Star Tree Services is a great way to educate yourself. Tree Branches & Twigs The branches grow from the trunk of the tree and they help support the flowers, fruits and leaves the tree produces. The twigs and branches are also used as transport between the trunk and leaves. The top part of the tree along with the leaves is called the tree crown. This area filters dust and other debris from the atmosphere. In addition to cleaning the air, the crown also offers shade for animals and humans alike. Tree Leaves The leaves of a tree manage the photosynthesis process which ensures the tree has food and maintains its health. The leaves are also tasked with drawing in carbon monoxide and releasing oxygen for the rest of us to use. Many leaves have different edges which work to collect water, repel pests, and reduce wind resistance. The Tree Trunk The trunk of every tree has five layers. These layers consist of the inner bark, the outer bark, heartwood, sapwood, and cambium cell. The outer bark protects from harsh temperatures and pests, in addition to helping the tree retain moisture. The inner bark, specifically the phloem is the digestive system that passes the food through to other parts of the tree. This part of the tree has a very short life, and it turns into cork before merging with the outer layer of bark when it dies. The cambium cell layer produces new tree bark and wood as the tree grows and this is generated from the hormones that come from the leaves and pass to the inner layer. Sapwood is tasked with moving water to the leaves of the tree and as the wood ages, it transforms into heartwood, which is in the tree center. The heartwood is the main support of the tree structure and though it no longer grows, it won’t decay or become frail as long as it is protected by the outer layers. The Tree Root System One of the most important parts of the tree is its root system. These are found in the first three feet of soil around the tree and can extend as much as four times further away than the total circumference of the tree crown. The roots collect minerals and water from the ground, store food for the tree, and help secure it to its spot in the ground.
