The structure and composition of the hard fibrous substance that makes up the trunks and large branches of trees beneath the bark. Wood (Fig. 1) is composed mostly of hollow, elongated, spindle-shaped cells that are arranged parallel to each other along the trunk of a tree. The characteristics of these fibrous cells and their arrangement affect strength properties, appearance, resistance to penetration by water and chemicals, resistance to decay, and many other properties. Thus, wood anatomy is an important field of study for plant scientists, botanists, forest engineers, and manufacturers of lumber and other wood products.
