Wood is the xylem tissue of woody plants, notably trees but also shrubs. Wood from the latter is only produced in small sizes, reducing the diversity of uses. Wood is a hygroscopic, cellular and anisotropic material. Dry wood is composed of fibers of cellulose (40%?50%) and hemicellulose (20%?30%) held together by lignin (25%?30%).
