4 Frequently Asked Questions about "What is lignin in plants"

Why is lignin important?

Lignin and its related metabolism play important roles in the growth and development of plants. As a complex phenolic polymer, lignin enhances plant cell wall rigidity, hydrophobic properties and promotes minerals transport through the vascular bundles in plant .

Is lignin a polymer?

It is considered the second most abundant organic polymer on Earth, surpassed only by cellulose, and constitutes a significant portion of plant biomass. Lignin forms by cross-linking phenolic precursors, creating an intricate, amorphous structure.
