Question

Which of the following tissue has dead cells?

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

Answer 1

Answer: (B)

Sclerenchyma

Parenchyma cells have thin cellulosic cell walls. Collenchyma cells have thicker cellulosic walls and also may have pectin deposition in the corners. Sclerenchyma cells have thick lignified cell walls and are dead at maturity and provide protection to the different parts of the body. Epithelial cells are thin-walled and living.

So, the correct answer is option B.
