Question

__________ cells have lignified walls.

• A. Collenchyma
• B. Parenchyma
• C. Sclerenchyma

Answer 1

Sclerenchyma

Sclerenchyma cells have thick lignified walls. The lignified wall gives sclerenchyma cells their rigidity and helps in providing mechanical support. Collenchyma and parenchyma cells do not have lignified walls.

So, the correct option is C.
