lignin
n.
complex polymer which combines with cellulose to form the woody cell walls of plants (Biology)
Lignin
Lignin is a class of complex
organic polymers that form important 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 phenol polymers.
