sclerenchyma is a type of plant tissue that provides structural support. It is composed of thick, lignified cell walls, making it rigid and strong. This tissue is typically found in areas of the plant that require extra support, such as stems and seed coats. There are two main types of sclerenchyma cells: fibers and sclereids. Fibers are long and slender, while sclereids are shorter and irregularly shaped. Both types contribute to the overall strength and durability of the plant, helping it withstand various environmental stresses.
