Detailed explanation-1: -Sclerenchyma is a type of simple permanent tissue. Simple tissues are made up of a group of uniform cells having similar structures and perform the same function. Other than sclerenchyma, collenchyma and parenchyma are also simple tissues.

Detailed explanation-2: -Flax. Flax bast fiber cells are an ideal example of sclerenchyma fibers, with extraordinary cell wall thickness and length. Their major function is to provide strength to the long (1 m) and thin (2 mm) flax stem.

Detailed explanation-3: -This is in reference to the tough outer walls of sclerenchyma cells, which are lignified and made of tough material. Together, this hard cellular tissue serves as a major structural support for plants as they grow.

Detailed explanation-4: -Sclerenchyma cells are elongated, dead cells with lignin deposits in their cell wall. They have no intercellular gaps. Sclerenchyma is found in the covering of seeds and nuts, around the vascular tissues in stems and the veins of leaves. Sclerenchyma provides strength to the plant.
