Lignin Definition:
Water-conducting cells in vascular plants are lignified; that is, their cell walls are strengthened by the polymer lignin.

Lignin Notes:
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily. Chemically, lignins are cross-linked phenolic polymers. The composition of lignin varies from species to species.
