Open in App
Solution
The correct option is C Deplasmolysis
When a plant cell is placed in concentrated salt solution, water concentration inside the cell is greater than that which is outside the cell. Hence, water moves from inside the cell through the cell membrane into the surrounding medium. As a result, the protoplasm separates from the cell wall and assumes spherical shape. It is called plasmolysis.When such a plasmolysed cell is placed in a hypotonic solution, meaning, the solution having solute concentration lower than the cell sap, the water moves back into the cell because of the higher concentration of water outside the cell than in the cell. The cell then swells to become turgid and assumes original volume. It is called deplasmolysis.Thus, the correct answer is option (B).
