Question

The pressure exerted by wall of the cell on the protoplast is

• A. W.P.
• B. T.P.
• C. D.P.
• D. O.P.

Answer 1

The correct option is A W.P.

Wall pressure (W.P.) is the pressure applied by the cell wall on the contents of the cell. Wall pressure is opposite to the turgor pressure.

Turgor pressure (T.P.) is the pressure exerted by the cytoplasm on the cell wall.
Osmotic pressure (O.P.) is the force caused by a solution passing through a semi permeable surface by osmosis.

Thus, the correct answer is option (A).
