The cell walls of wood in trees self-assemble through structural features, not biochemistry.
A better understanding of how the cell wall of wood forms will someday help wood scientists assemble wood-like composites without using trees. The current hypothesis is that the cell wall of wood does not require biochemistry to form, but self-assembles spontaneously because of structural features. Researchers are studying this process carefully, in hopes that someday wood-like materials can be produced from other plant-derived molecules. (Courtesy of the Biomimicry Guild)
