Question

If turgor pressure becomes equal to the wall pressure, then

• A. Water leaves the cell
• B. Water enters the cell
• C. No exchange of water takes place
• D. Solute goes from the cell into water

Answer 1

Answer: (C)

No exchange of water takes place

When water enters the cell of a plant cytoplasm and exerts an outward pressure and that pressure is called turgor pressure. A cell wall is rigid and flexible therefore exerts an equal and opposite wall pressure against the expanding protoplasm. Thus, turgor pressure becomes equal to the wall pressure when no exchange of water takes place and equilibrium are established.

So, the correct answer is option C.
