Hint: It is a permanent tissue whose cells are dead. They are long and thin because the walls are thickened due to lignin. This tissue makes the husk hard and thick.

Complete step by step solution: To answer this question, at first, we have to know the composition of the coconut husk. The husk of the coconut is composed of sclerenchymatous tissue. It is found in the mesocarp of coconut and yields a coir known as the fibre used for making different things like mats, ropes, cords e.t.c. Sclerenchymatous tissue is found in stems( around the vascular bundle) , roots, a vein of leaves, tough coverings of seeds. These tissues are taken as thick-walled, lignified, supportive tissue characterized by the absence of living protoplast. It is referred to as supportive tissues of a plant. They are recognised to have extremely thick cell walls and do not participate in many of the different activities of the developing plant. The characteristic of sclerenchymatous tissue is specifically mechanical & protective. This tissue provides strength, rigidity, flexibility of the plant body.

Additional Information:
Sclerenchyma tissue, whilst mature, consists of dead cells which have heavily thickened walls containing lignin and excessive cellulose content (60%-80%), and serves the characteristic of providing structural support in plants. Sclerenchyma cells possess' two kinds of cell walls, such as primary and secondary walls

Note: The tissues which are specialized to secrete products are known as special tissues. These secreted substances may be useful or might not be useful to plants.
