Question

A cell is plasmolysed after being kept in a hypertonic solution. What will be present between the cell wall and plasmalemma?

• A. Isotonic solution
• B. Hypertonic solution
• C. Air
• D. Hypotonic solution

Answer 1

Answer: (B)

Hypertonic solution

The cell wall is non-living and cannot regulate the entry and exit of solute or solvent molecules. When a cell is kept in hypertonic solution, it readily crosses the cell wall and fills the space between the cell wall and cell membrane. This hypertonic solution in direct contact with the cell membrane causes plasmolysis and extracts water from the cytoplasm of the cell.

So, the correct answer is option B.
