Question: 1 / 715

What characterizes sclerenchyma cells in plants?

Cells with thin cell walls for flexibility

Cells that transport water and nutrients

Cells that have lignified walls for structural support

Sclerenchyma cells are characterized by having lignified walls, which means their cell walls are fortified with lignin. This lignification makes the walls much thicker and rigid compared to other types of plant cells. The primary function of sclerenchyma is to provide structural support to plants, enabling them to maintain their shape and withstand various stresses.

Their thick, hard cell walls help in reinforcing the plant structure, which is particularly important in areas that experience mechanical stress, like stems and vascular tissues. Unlike cells with thin walls that provide flexibility, or cells specialized for transport or photosynthesis, sclerenchyma's role is specifically focused on support and strength.
