Wood is a complex biological structure, a composite of many chemistries and cell types acting together to serve the needs of a living plant. There is no property of wood—physical, mechanical, chem­ical, biological, or technological—that is not fundamentally derived from the fact that wood is formed to meet the needs of the living tree.

Wood has evolved over the course of millions of years to serve three main functions in plants? conduction of water from the roots to the leaves, mechani­cal support of the plant body, and storage of biochemicals. To accomplish any of these functions, wood must have cells that are designed and interconnected in ways sufficient to perform these functions.

Understanding the basic requirements dictated by these three functions and identifying the structures in wood that perform them allow insight to the realm of wood as an engineering material.
