Ultimate Tree Guide - Everything You Need to Know About a Tree
Trees are literally everywhere. A tree is the most obvious and remarkable plant you will see when you venture outside. People are infinately curious about trees in a forest or a tree in their yard. This tree guide will enable you to satisfy that curiosity and explain a tree in detail.

A Tree's Tissue
Tree tissues are made up mostly of three basic groups: dermal tissue (bark), ground tissue (roots) and vascular tissue (under bark). To understand a tree, you must understand its tissue.

How Much of a Tree is Alive?
Only 1% of a tree is actually alive, composed of living cells. The only living portion of a tree is a thin film of cells just under the bark called the cambium, root tips, buds and leaves.

How Much Oxygen Do Trees Make
Trees make oxygen in amounts that contribute to its availability to humans. There are questions as to how much oxygen is available to humans that is tree produced

How A Tree Absorbs and Uses Water
Trees use massive amounts of water through the process of transpiration for the benifit of themselves and the Earth.

Parts of a Tree - The Leaf
Leaves are food factories of the tree. Powered by sunlight, the green substance in leaves called chlorophyll uses carbon dioxide and water to produce carbohydrates.

Parts of a Tree - The Fruit
Besides its branches, roots, and leaves, a mature tree grows another important structure - the flower (or cone, in the case of evergreens).

Parts of a Tree - The Twig
Believe it or not, twigs can be used to identify a tree. Good thing because they are about all you have during the dormant months of winter.

Parts of a Tree - The Bark
Bark is a tree's natural armor and protects from external threats. Bark also has several physical functions, one is ridding the tree of wastes by absorbing and locking them into its dead cells and resins.

Parts of a Tree - The Shape or Silhouette
Ok, so the shape is not really a part. Still, it is a distinguishing feature of a tree and another way to help in its identification.

Ten Top Reasons Why Trees Are Important
Trees are both important and valuable to our very existence. It would not be too hard to believe that without trees we humans would not exist on this beautiful planet.
