Husk of coconut is made of
The coconut’s husk is made up of sclerenchyma tissue.
The stiffness that plants have is a feature of the schlerenchyma tissue. These tissues have dead cells in them and are narrow and long in appearance for e.g. Coconut. Lignin thickens the wall of the dead cells that compose these tissues. It works as a cement in its characteristics. The various places where schlerenchyma tissue can be found are the casing of the nuts and seeds, stem of the plants, and in the leaf veins in the vascular bundle structure. The main function it serves is to provide firmness and strength to the plant.
