Question

Which cellular structure provides resistance to microbes to withstand hypotonic external media without bursting?

• A. Cell membrane
• B. Cell wall
• C. Mitochondria
• D. Ribosome

Answer 1

The correct option is B Cell wall

A hypotonic solution is a solution, which contains a lesser solute concentration. When any cell is kept in a hypotonic solution, then endosmosis occurs where water moves inside the cell from its surroundings and the cell swells up and later bursts. But, if the cell possesses a cell wall surrounding the cell membrane then endosmosis occurs but the cell does not burst because it provides tensile strength and protection against mechanical and osmotic stress.

So, the correct answer is 'Cell wall'.
