puuaineeseen
Puuaineeseen refers to wood substance, the primary organic structural material of trees and shrubs. It is a complex composite material, mainly composed of cellulose fibers embedded in a matrix of lignin. Cellulose, a polysaccharide, provides tensile strength, while lignin, a polymer, offers compressive strength and rigidity. The cell walls of wood are formed by these two components, along with hemicellulose, which acts as a binding agent.
The properties of puuaineeseen vary significantly depending on the tree species and its growth conditions. Factors
