Question

Which of these is a living cell?

• A. Tracheid
• B. Xylem vessel cell
• C. Xylem parenchyma cell
• D. Xylem sclerenchyma cell

Answer 1

The correct option is C

Xylem parenchyma cell

The correct answer is option C.

The explanation for the correct answer

Option C - Xylem parenchyma cell

1. They are thin-walled cells.
2. They surround the tracheids and xylem vessels.
3. They are living cells and help in the conduction of water and minerals up to the cell.

The explanation for the other options.

Option A - Tracheid

1. They are long, dead cells with a tapering end.
2. They are narrower than xylem vessels.
3. Their cell walls are thick and have many pits and depression.

Option B - Xylem vessels

1. Xylem vessels are long dead cells present end to end.
2. The main function of this cell is the conduction of water.

Option D - Xylem sclerenchyma cell.

1. They are long narrow dead cells.
2. They provide support to the plant.

Hence, the xylem parenchyma cell is a living cell.
