Quizplus · Accepted Answer

Pectin is a complex polysaccharide that helps in providing flexibility to the primary walls of collenchyma cells. Cellulose, on the other hand, is a major component of the plant cell wall but does not provide flexibility. Lignin and fiber contribute to the strength and rigidity of the cell wall, while the cuticle is a waxy layer that covers the outer surface of the epidermis and is not directly involved in cell wall structure.
