Explanation:
Detailed explanation-1: -Sclerenchyma cells have thickened lignified walls, which make them strong and waterproof. They are commonly classified into support types and conducting forms. Support sclerenchyma is comprised of sclereids and fibers. This tissue reduces wilting, but it is energetically costly for the plant to create.
Detailed explanation-2: -Sometimes known as stone cells, sclereids are also responsible for the gritty texture of pears and guavas.
Detailed explanation-3: -B. Collenchyma has flexible cell walls that can elongate better than sclerenchyma. C. Collenchyma cells are stronger and more rigid than sclerenchyma cells.
Detailed explanation-4: -Sclerenchyma cells are the strongest plant cell type.
