Composition of a Tree

Trees are among the most important natural resources on earth. Without them, this planet wouldn’t be inhabitable. All living creatures need trees to survive, and trees want sunlight, nutrients, and water to live healthy lives. There are many more fascinating facts about trees to learn, but a wonderful place to begin is using a tree’s basic anatomy. Continue reading to find out the 4 basic sections of a tree and the way they operate together to support healthier growth.

Green Leaf TreeLeaves

A tree’s leaves are what we¬†see the most. Their lovely springtime blooms bring new greenery to our surrounding environments. From leaves and flowers, to fruits and nuts, the yields of a canopy are frequently revered parts of trees. But leaves serve a lot bigger purpose than aesthetics; they are the food factories of the shrub. The green color we see in leaves is the result of a chemical named chlorophyll. This procedure is known as photosynthesis, and the two trees and living animals want it to survive. Without it, trees couldn’t give the much-need oxygen we want!


Behind tree foliage, you’ll find its branches and twigs. They develop and outward from the tree trunk, and provide a supportive base for leaves and other yields. But they also play important role in transferring nutrients and water back and forth from the back and the canopy.


The tree trunk has 5 separate layers, all that serving an important function. Beginning from the outside and working our way in, these layers include the bark, inner bark, cambium cell layer, sapwood, and heartwood. Outer bark prevents moisture and rain in wet seasons, and keeps it in warm seasons. Inner bark can also be referred to as phloem, and serves as a food pipeline. The cambium cell layer is the part of the trunk that’s growing, sapwood is the tree’s water pipeline, and heartwood is actually deadwood, but it functions as a tree’s principal support structure.


The tree roots are at which minerals and water are recovered from the soil and sent upwards through the tree, all of the way to the leaves. Roots are only as deep as the first 3 feet of soil, therefore it is essential that they remain free from harm, including lawn mowers, weed whackers, construction, and more.
