Detailed explanation-1: -Collenchyma. Collenchyma cells have thick walls that are especially thick at their corners.
Detailed explanation-2: -Sclerenchyma: Sclerenchyma have thick, nonelastic secondary cell walls and are dead at maturity. Sclerenchyma cells support and strengthen nonexpanding tissues of the plant such as mature roots, stems, and leaves.
Detailed explanation-3: -Sclerenchyma is a simple permanent tissue with thick secondary lignified cell walls.
Detailed explanation-4: -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-5: -Sclerenchyma tissue possesses long, narrow cells with thickened walls. They possess secondary walls made of lignin.
