22. Growth and Life Cycle of a Tree
The easiest way to find out information on a trees life cycle is by looking at its tree rings. You can tell a lot about what a tree endured and how long it lived for by looking at this. Like most things, trees need the basic necessities to grow. They need water, good soil, nutrients, and food; which in this case would be from photosynthesis.

23. Anatomy of a Tree
The outer bark is the tree's protection from the outside world.
The inner bark, or "phloem", is pipeline through which food
is passed to the rest of the tree.
C. The cambium cell layer is the growing part of the trunk.
D. Sapwood is the tree's pipeline for water moving up to the
leaves.
E. Heartwood is the central, supporting pillar of the tree.
Although dead, it will not decay or lose strength while the
outer layers are intact.
