Does Sclerenchyma Have Lignin?

Sclerenchyma tissue, when mature, is composed of dead cells that have heavily thickened walls containing lignin and a high cellulose content (60%–80%), and serves the function of providing structural support in plants.

What is the cell wall of sclerenchyma made up of?

The cell walls of sclerenchyma have thickened secondary layers made from cellulose, hemicelluloses and lignin. The stiffness of sclerenchyma depends on the orientation of cellulose and varies widely under developmental control.

Do vessels have lignin?

Vessels are made of a substance called lignin. They have a lignified cell wall and a central cavity. Vessel members are interconnected through perforations in their common walls. Lignin is a hard organic polymer.
