A cell is equally permeable to sucrose solution and NaCl solution. First the cell is put in 0.6 M sucrose solution there is no change in size but when put in 0.6 M NaCl solution the size will

Options

  1. Aincrease
  2. Bdecrease
  3. Cremain same
  4. Dcan't be said.

Correct answer

B. decrease

Step-by-step solution

0.6 M NaCl solution is hypertonic to 0.6 M sucrose solution because there are more solutes per unit volume in NaCl solution as compared to sucrose solution. Hence, when the cell is placed in 0.6 M NaCl solution after being placed in 0.6 M sucrose solution water will move out of it and its size will decrease on account of exosmosis.
