Question

Collenchyma differs from sclerenchyma in

• A. Having suberin rich cell wall and protoplasm
• B. Having lignified cell wall and protoplasm
• C. Not having protoplasm and pectin in cell wall
• D. Having pecto-cellulosic cell wall and protoplasm

Answer 1

The correct option is D Having pecto-cellulosic cell wall and protoplasm

Collenchyma cells contain protoplasm and do not have any intercellular gaps. Sclerenchyma is made up of dead cells with thick walls. The cells are alive and have protoplasm at first, but as impermeable secondary walls (lignin) form, they become dead, thick, and rigid.
