Detailed explanation-1: -Sclerenchyma is a simple permanent tissue with thick secondary lignified cell walls.
Detailed explanation-2: -SCLERENCHYMA. Sclerenchyma cells have thick, lignified secondary walls, lack cell contents at maturity, and occur throughout all plant tissues. These features make sclerenchyma tissues hard, rigid, and somewhat brittle.
Detailed explanation-3: -6.3.2.3 Sclerenchyma Tissue Sclerenchyma cells possess two types of cell walls: primary and secondary walls. The secondary wall is very thick and highly lignified (15%–35%) and imparts a great rigidity and hardness to the cell and tissue. There are two main types of sclerenchyma cells: fibers and sclereids.
Detailed explanation-4: -The cell walls of sclerenchyma have thickened secondary layers made from cellulose, hemicelluloses and lignin.
Detailed explanation-5: -Sclerenchyma tissue possesses long, narrow cells with thickened walls. They possess secondary walls made of lignin. Lignin is a chemical substance, which acts as cement and hardens them.
