While observing a thin section of plant stem, four students sketched sclerenchyma as the following : Which one of theme is the correct observation??

a) Compactly arranged cells.

b) Lignified , thick walled cells

c) Thick walled cells without nucleus

d) All of the above.

 it is option B) ,because 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.

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.

 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.
