Detailed explanation-1: -The main function of sclerenchyma is to provide mechanical support and strength to the plants. They provide structural support to the plant organs.

Detailed explanation-2: -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-3: -Sclereids are the sclerenchyma cells with very thick secondary wall deposits and provide mechanical support.

Detailed explanation-4: -Walls of the tissues are thickened due to the deposition of lignin.

Detailed explanation-5: -The cells of this tissue are dead. The walls are thickened due to lignin. Lignin is a chemical substance which acts as cement and hardens them. Thus, due to deposition of lignin sclerenchyma tissue provides mechanical strength to the plant parts.
