Husk of a coconut is made of ____ tissue.

Scherenchyma

The correct answer is Option (3) – Scherenchyma

The husk of a coconut is made of sclerenchyma tissue. Sclerenchyma tissue is a type of complex permanent tissue that provides structural support and protection to plants. It is made up of thick-walled cells that are dead at maturity. The thick cell walls are due to the presence of lignin, a complex carbohydrate that makes the cells rigid .

• Collenchyma: This tissue also provides support but is found in growing stems and leaves. It has unevenly thickened cell walls containing pectin but not lignin.
• Xylem: This tissue is responsible for transporting water and minerals throughout the plant. It is composed of tracheids and vessel elements, which are elongated cells with lignin-encrusted walls.
• Parenchyma: This is the most common type of plant tissue and has thin cell walls. It is involved in various functions such as photosynthesis, storage, and secretion.
