Question

Quizplus · Accepted Answer

The presence of lignin is characteristic of plant cell walls that have stopped growing and actively dividing. Lignin provides structural support and rigidity to the cell wall, making it stiffer and more resistant to bending or collapsing. Pectin and cellulose are also important components of plant cell walls, but they are present in varying amounts depending on the stage of growth and development of the cell. Glue-like polysaccharides and a gluey matrix containing rope-like strands are not commonly found in plant cell walls.
