Question 12 — Coconut husk fibres are - Tissues in Action - [Teachoo] - Questions at the end of the chapter
Coconut husk / coir mat — needs strength
Sclerenchyma — thick lignified walls Y
Parenchyma — thin walls, soft X
Only sclerenchyma gives lasting strength
View Answer Hide Answer

The strength comes from sclerenchyma , whose cells have thick walls hardened with lignin, making them tough and fibrous.

Living parenchyma has thin walls and is soft, with loosely packed cells that store food. It cannot bear strain or give the hard, lasting strength needed for mats, so it could not replace sclerenchyma.

Why Coconut Husk Is Tough
Sclerenchyma
Thick walls hardened with lignin — tough and fibrous.
↓
Parenchyma
Thin-walled, soft, loosely packed cells.
↓
Only sclerenchyma can bear the strain
