allerySclerenchyma cells are characterised by:
AThin walls and being alive at maturity
BCorner-thickened walls and elastic flexibility
CThick lignified walls and dead at maturity
DCellulose-only walls and large central vacuoles
Answer & Solution
Correct answer: C. Thick lignified walls and dead at maturity
SCLERENCHYMA = thick LIGNIFIED secondary walls; DEAD at maturity.
Provides rigid mechanical support (fibres in jute, coconut husk; sclereids in pear).
Parenchyma is alive, thin-walled; collenchyma has corner thickening.
