The concentration of solute in four cells is 0.4M0.4 \mathrm{M}. They are placed in four separate containers I, II, III and IV, filled with saline water of concentrations 0.1M,0.4M,2M0.1 \mathrm{M}, 0.4 \mathrm{M}, 2 \mathrm{M} and 3M3 \mathrm{M} respectively. In which container will the cell swell?

Options

  1. AContainer I
  2. BContainer II
  3. CContainer III
  4. DContainer IV

Correct answer

A. Container I

Step-by-step solution

When cell having solute concentration of 0.4M0.4 \mathrm{M} is placed in a saline water of concentration 0.1M0.1 \mathrm{M}, the outer medium, i.e., the saline water is hypotonic to the cell. Hence, the water will move inside the cell (endosmosis) and as a result the cell will swell up.
