Question

A freshly plasmolysed cell has

• A. Little solute potential
• B. Maximum turgor pressure
• C. Zero turgor pressure
• D. Negative turgor pressure

Answer 1

Answer: (D)

Negative turgor pressure

Plasmolysis is the process in which cells lose water in a hypertonic solution. When a cell is kept in hypertonic solution, the cell will loose water and will shrink. This will results in plasmolysed cell. It has maximum solute potential. During plasmolysis, the turgor pressure of cell decreases. Hence, in a freshly plasmolysed cell, the turgor pressure or pressure potential is negative.

Thus, the correct answer is option D.
