Question

Given below is the diagram of a plasmolysed cell kept in a hypertonic solution. The space between the shrunken protoplast and the cell wall marked by the letter A contains ______.

• A. pure water
• B. hypertonic solution
• C. air
• D. cell sap

Answer 1

The correct option is B hypertonic solution

In plasmolysis, water moves out of the cell. Thus, the protoplast (the cell minus the cell wall) shrinks away from the cell wall. Since the cell wall is permeable, the hypertonic solution moves in and fills this space.
