Trees/Plants
Different Parts of the Tree
Diagram A: The Outer Bark: This part of the tree is basically a shell that protects the rest of the tree, it constantly dies and reforms from the inside. It also has pores spread sporadically all over it, that absorb carbon dioxide
Diagram B: The Inner Bark: This part of the tree spreads food around the trunk, it only lives for a short time, then it turns into cork and becomes part of the outer bark.
Diagram C: The Cambium Cell Layer: This is the growing part of the tree that makes the new bark and makes new wood ever year to keep it moving/growing.
Diagram D: The Sapwood: This is a pipeline for water, it finishes developing around the time the Inner Bark dies. As new rings of sapwood are grown, the inner rings die and become Heartwood.
Diagram E: The Heartwood: This part is the support beam for the entire tree. It is made up of old, dead sapwood, when the sapwood reproduces, more wood is added to the heartwood. As long as the Outer Bark is alive, this wood won't decay.

Trees and Oxygen
It is a common myth that trees inhale carbon dioxide and exhale oxygen, but what actually happens is much more complicated.
When us animals exhale carbon dioxide, trees are able to absorb it through the pores in their outer bark.
Then, they absorb water and the oxygen in the water, through their roots.
Finally, they get energy from the sun with photosynthesis. (Through their leaves).
Then, the tree will mix them together, and it will create carbohydrates for feeding itself. It will then release the excess oxygen, (from the water), into the air, which we then breathe in, and the cycle continues.
