Question

Answer

Husk of coconut is made up of sclerenchymatous tissue.

It is present in mesocarp of fruit of coconut and a yield a coir a well known fibre used for making mats, ropes, cords, brushes e.t.c.

Sclerenchymatous tissue are found in stems( around the vascular bundle) , roots, vein of leaves, hard coverings of seeds and nuts.

The function of sclerenchymatous tissue is mainly mechanical & protective. It gives strength , rigidity ,flexibility and elasticity to the plant body.

Answer

answer is b sclerenchymatous

Answer

Sclerenchyma tissue makes up the husk of coconut.

Answer

Husk of Coconut: A Sclerenchymatous Tissue

The husk of a coconut is composed of various tissues that serve different functions. One of these tissues is the sclerenchyma tissue, which makes up the outermost layer of the coconut husk.

Sclerenchyma Tissue:
Sclerenchyma tissue is a type of permanent tissue found in plants. It provides mechanical support and protection to the plant. This tissue is composed of thick-walled cells with lignified secondary cell walls. These thick walls provide strength and rigidity to the tissue.

Characteristics of Sclerenchyma:
- Thick cell walls: Sclerenchyma cells have thick cell walls, which are often impregnated with lignin, a complex polymer that provides additional strength.
- Dead at maturity: Unlike other plant cells, sclerenchyma cells are dead at maturity. This is because the thickened cell walls prevent the exchange of gases and nutrients between cells.
- Lack of protoplast: The protoplast (living contents) of sclerenchyma cells disintegrates during cell development, leaving behind only the thick cell wall.

Function of Sclerenchyma in Coconut Husk:
The sclerenchyma tissue in the husk of a coconut provides mechanical support and protection to the inner layers of the fruit. The thick-walled cells of the sclerenchyma tissue help maintain the shape and structure of the husk, even when exposed to external forces such as wind or impact. This protective layer prevents damage to the inner layers of the coconut.

Other Tissues in Coconut Husk:
While the husk of a coconut is primarily composed of sclerenchyma tissue, it also contains other tissues such as:
- Epidermis: The outermost layer of the husk, composed of thin-walled cells that provide a protective covering.
- Parenchyma: This tissue is found beneath the epidermis and is involved in storing water and nutrients.
- Vascular tissue: The husk also contains vascular tissue, which is responsible for transporting water, nutrients, and sugars throughout the plant.

Conclusion:
In conclusion, the husk of a coconut is composed of different tissues, one of which is the sclerenchyma tissue. Sclerenchyma tissue provides mechanical support and protection to the coconut husk. Its thick-walled cells with lignified secondary cell walls make the husk strong and rigid.
