lignin
lignin A complex, cross-linked polymer, comprising phenyl propene units, that is found in many plant-cell walls. Its function appears to be to cement together and anchor cellulose fibres and to stiffen the cell wall. Lignin reduces infection, rot, and decay. It is among the most chemically inert of plant substances and survives in fossils of woody stems.

lignin A complex organic polymer that is deposited within the cellulose of plant cell walls during secondary thickening. Lignification makes the walls woody and therefore rigid. See sclerenchyma.
