Did you know that there are over three trillion trees in the world with almost half of them living in tropical or subtropical forests? That equates to roughly 400 trees for every human. Ever wonder what parts make up a tree?
There are five parts of a tree. Here is the make-up of those three trillion trees.
The top of the tree is the crown, which is made up of the leaves and branches. The crown has numerous jobs:
The crowns of trees come in many shapes and sizes!
The part of the tree that grows underground is the roots. Trees have a lot of roots — the size of the root system is usually as big as the part of the tree above the ground. This is essential because the roots help support the tree so it won’t fall over. Can you imagine how many roots it takes to hold up a 100-foot tree!
In addition to keeping the tree from tipping over, the main job of the roots is to collect water and nutrients from the soil and to store them for times when there isn’t as much available.
Leaves are considered part of the crown of a tree which is at the top. Leaves are an essential part of the tree that converts energy into food, which is mostly sugar. Leaves are the food factories of a tree, and they contain chlorophyll which gives leaves their green color. Chlorophyll is a critical biomolecule, used in photosynthesis which leaves use the sun’s energy to convert carbon dioxide from the atmosphere and water from the soil into sugar and oxygen. The tree’s food or sugar is either used or stored in the roots, trunk, and branches. The oxygen from this process is released back into the atmosphere.
Without the branches, there would be no support to distribute the leaves efficiently for the type of tree and the environment. The branches serve as conduits for water and nutrients and as storage for extra sugar.
The tree gets its shape and support from the trunk which holds up the crown. The trunk is the main transportation water and nutrients from the soil and sugar from the leaves. The bark, cambium, heartwood, phloem, and xylem are the five different layers that make up the trunk.
Parts of the Trunk
There are several rings inside the trunk of a tree. A new ring is added each year of the tree’s life that is why many people refer to them as the annual rings. These rings are made up of five parts:
The bark is the outside layer of a tree trunk, branches and twigs of trees and serves as a protective layer for the more delicate inside the wood of the tree. A tree has both an inner and outer bark. The inner layer of bark is made up of living cells, and the outer layer is made of dead cells, sort of like our fingernails.
The inner layer of bark is called phloem, and its main job is to carry sap full of sugar from the leaves to the rest of the tree.
The cambium is the thin layer of living cells just inside the bark. It makes new cells allowing the tree to grow wider each year.
Sapwood or xylem is made up of a network of living cells that bring water and nutrients up from the roots to the branches, twigs, and leaves.
In the center of the trunk is the heartwood is dead sapwood. It is the hardest wood of the tree, giving it support and strength. It is darker than sapwood.
In the center of the tree trunk, pith is the tiny dark spot of spongy living cells. Essential nutrients are carried up through the pith. Being in the center allows it to be protected from damage by insects, the wind or animals.
