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: -Sclerenchyma has lignified cell wall.

Detailed explanation-3: -Sclerenchyma is a simple permanent tissue with thick secondary lignified cell walls.

Detailed explanation-4: -lumen are cavities present inside the cell, cells of sclerenchyma tissue have narrow lumen because sclerenchyma are strongly lignified which lead to compressing the cell and thus only narrow cavity is left.
