Question
Name the tissues whose cells are thickened with:
a) Cellulose and pectin.
b) Lignin.
a) Cellulose and pectin.
b) Lignin.
Answer
a) Cellulose and Pectin - Collenchyma: Collenchyma cells are a type of ground tissue in plants that provide support to growing plant parts.
b) Lignin - Sclerenchyma: The tissues whose cells are thickened with lignin are sclerenchyma cells. Sclerenchyma cells are known for their rigidity and strength. Lignin deposition in their cell walls provides mechanical support to plant structures such as stems, roots, and vascular tissues.
