Lignin is concentrated in the compound middle lamella (CML) and is responsible for bonding adjacent cells together, providing structural integrity to wood. However, the S2 layer of the secondary cell wall contains the highest cellulose concentration, which is crucial for tensile strength. These distinct distributions reflect the complementary roles of lignin and cellulose in maintaining the mechanical properties of wood.
Which one of the following can be properly inferred from the information above?
Answer:
