Sclerenchyma is the supportive tissue in plants composed of hard, woody cells.
Sclerenchyma cells play a vital role in plant structure. Here's a more detailed breakdown:
- Supportive Tissue: According to the provided reference, sclerenchyma functions as a primary supportive tissue within plants.
- Hard, Woody Cells: It is composed of cells that are typically described as hard and woody due to the presence of lignin.
- Dead at Maturity: Sclerenchyma cells are usually dead when they reach maturity. The reference highlights that these cells have heavily thickened secondary walls.
- Lignin: The secondary walls of sclerenchyma cells contain lignin, which is a complex polymer that adds rigidity and strength.
