Four cells with osmotic potential equivalent to that of 3% salt solution were immersed respectively in solutions of different concentrations labeled as follows:

  • I= 4% salt solution;
  • II = 6% salt solution
  • III = 1% salt solution;
  • IV = 10% salt solution;
  • V = 5% salt solution.

Which of the solution will cause an increase in osmotic pressure within the cell?

  • A. I
  • B. II
  • C. III
  • D. IV
  • E. V.

Ans: ……C. III
