Sclerenchyma Tissue Vector Illustration

Sclerenchyma is a type of plant tissue that provides structural support to plants. It is composed of cells with thick, lignified secondary cell walls, which are reinforced with a tough, waterproof substance called lignin. These cells are dead at maturity and lack protoplasts, giving them a rigid and durable nature. Sclerenchyma cells are commonly found in the stems, roots, and leaves of vascular plants, contributing to their strength and rigidity.
