Mention the special features of sclerenchyma tissue.

Structure : Sclerenchyma consists of long and narrow dead cells.The cells of this tissue are thick-walled due to the deposition of lignin. The walls are so thick that there are no intercellular spaces.

Location : Sclerenchyma is present in stems, around the vascular bundles, in the veins of leaves and in the hard covers of seeds and nuts.The husk of a coconut is also made up of this tissue.

Functions : Some important functions of sclerenchyma are as follows:

• Sclerenchyma is tough and rigid; hence, it provides mechanical strength to a plant.

• It gives flexibility and elasticity to the various parts of a plant.
