Sclerenchyma tissue provides strength to coconut husk fibres because of thick lignified walls. Living parenchyma cells have thin walls and soft structure mainly for storage, so they cannot provide the hardness, toughness and durability needed for mats.
Coconut husk fibres are used for mats which are tough and fibrous. Which tissue has structural features suitable for providing this strength? Explain why living parenchyma couldn’t serve the same purpose.

Coconut husk fibres contain sclerenchyma tissue, which has thick, lignified and dead cells that provide great strength, hardness and durability. These characteristics make the fibres suitable for tough mats and ropes. Parenchyma tissue could not serve this purpose because its living cells have thin walls, soft texture and mainly perform storage and photosynthesis instead of providing rigid mechanical support.
