Question

Compare the statements A and B.

Statement A: To counteract the increase in turgor pressure in plant cells, the cell wall produces an equal and opposite pressure, i.e. wall pressure.

Statement B: When plant cells undergo endosmosis, they swell but do not burst.

• A. Statement A is wrong and B is correct.
• B. Both statements A and B are correct, and A is not the reason for B.
• C. Both statements A and B are correct, and A is the reason for B.
• D. Statement A is correct and B is wrong.

Answer 1

The correct option is C

Both statements A and B are correct, and A is the reason for B.

When water enters the living cell, a pressure is developed within the cell due to turgidity.

The hydrostatic pressure developed inside the cell on the cell wall due to endosmosis is called turgor pressure.

When the wall pressure equals the turgor pressure, the entry of water into the cell stops. Therefore, the cell wall does not burst and the cells swell.
