Question

Pressure on plant cell wall caused by the osmotic movement of water is called

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

Answer 1

Answer: (C)

Turgor pressure

When a plant cell is placed in the hypotonic solution, it causes endosmosis i.e. movement of surrounding water into the cell. This creates a turgor pressure against the rigid walls due to the entry of water.

Osmotic pressure is the hydrostatic pressure developed in a solution when it is separated from the pure solvent by a semi-permeable membrane in a rigid vessel.

Hence, the correct answer is 'Turgor pressure'.
