How do trees make wood?

Trees grow by forming new building blocks. Every building block has a structure and purpose. The building blocks are cells and tissues that form sapwood. The sapwood carries the water and food up and down the tree. When it is old, the sapwood becomes heartwood.

Anthony Brach Ph.D.

Cells in a thin layer, called the cambium, just under the bark, divide to produce new wood in the tree.
