Question

A cell kept in solution increases in volume. The solution is

• A. Hypotonic
• B. Isotonic
• C. Hypertonic
• D. Either A or B

Answer 1

The correct option is A Hypotonic

A cell increases in volume if the external medium is hypotonic because a hypotonic solution has more concentration of solvent molecules than the fluid inside the cell. So, the solvent molecules move inside the cell from the region of higher concentration to the lower concentration by the process of endosmosis. The cell swells and increases in size.

So, the correct answer is option A.
