The wood ina living tree is composed of specialized tissues and mechanical support. The cells are glued together with lignin. Biogenesis of the wood cell wall follows a peculiar pathway leading to an intelligent composite structure of cellulose, hemicelluloses and lignin. Strong, anisotropically oriented cellulose microfibrils are embedded in a matrix of lignin and hemicellulose wall. In addition to the cell wall polymer, wood contains extractives that preserve it against microbes and serve as reserve of carbon and energy. In this course the different aspects in the structure, chemistry and functions of wood are discussed in details with links to their technical improtance in forest products technology.
