Question

Name the tissue that is present in the husk of coconut.
A) Sclerenchyma
B) Parenchyma
C) Collenchyma
D) Aerenchyma

Answer 1

Hint:The husk of coconut is the outer covering of the coconut which is brown in colour, hard, rough and made up of dead cells.

Complete Answer:
>Sclerenchyma:-Sclerenchyma is the dead and supporting tissue of a plant.The only function of the sclerenchyma is to make the plant hard and stiff. The cells of sclerenchymatous tissue have thick lignified secondary cell walls.
>Parenchyma:-Parenchyma is the functional and living tissue present in plants. Parenchyma cells have thin primary walls.These tissues normally found in the soft parts of plants. Parenchyma perform many tasks such as photosynthesis or storing.
>Collenchyma:-Collenchyma is also the living tissue of plants.This tissue is made up of elongated cells having irregular cell walls. It also provides support to the plant.
>Aerenchyma:It is a soft tissue of a plant.This tissue contains air spaces and it is mainly found in aquatic plants in order to provide them buoyancy.

As we have seen in the above discussion, Sclerenchyma is the dead and hard tissue of a plant. And we have already mentioned in the hint that husk of coconut is made up of dead cells and it is hard and stiff. So, by this we can conclude that the tissue that is present in the husk of coconut is Sclerenchyma.

Hence, the correct answer is option ‘A’.

Note: Remember that husk of coconut is the outer hard covering of coconut. One can identify it easily that it is sclerenchymatous due to its hardness and stiffness.
