Question

Passage of water through a semipermeable membrane increases ............. inside the cell.

• A. Suction pressure
• B. Osmotic pressure
• C. Turgor pressure
• D. Wall pressure

Answer 1

Answer: (C)

Turgor pressure

When a cell absorbs water, the water starts exhibiting a pressure on the cell membrane and cell wall which is known as turgor pressure.

Osmotic pressure is what causes movement of water from its high concentration to low concentration.

Wall pressure is the pressure exhibited by the cell wall when it experiences turgor pressure.

Suction pressure is created when fluid is removed from one place and the fluid from another place rushes to balance the pressure.

So the correct answer is 'Turgor pressure'.
