WebThe sclerenchyma tissue is a solid tissue. It is a non-living tissue. The cells of these tissues are thickened by a substance called lignin, in addition to cellulose. It also strengthens and supports the plant, giving it elasticity and hardness. Complex tissues Examples of complex tissues in plants are vascular tissues and conductive tissues. Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
