Which one of the following tissues in plants is usually without protoplast and regarded as dead cells?

Options

  1. ACollenchyma
  2. BParenchyma
  3. CSclerenchyma
  4. DXylem parenchyma

Correct answer

C. Sclerenchyma

Step-by-step solution

Sclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits. They are usually dead and without protoplasts. Parenchyma and collenchyma are living tissues. Xylem parenchyma is the only living component of xylem. Answer: Sclerenchyma
