CAUTION A cell is placed in a solution that is hypotonic to the cell. Which of the following best describes movement of water in this situation?
a. Water will only flow into the cell.
b. Water will only flow out of the cell.
c. Water will flow into and out of the cell, but the overall net movement will be out of the cell.
d. Water will flow into and out of the cell, but the overall net movement will be into the cell.
Introduction:
A hypotonic solution is a solution containing low solute concentration in the cell’s exterior in comparison to cell’s interior.
Answer to Problem 1TYK
Correct answer:
The water will flow inside and outside of the cell when it is placed in a hypotonic solution. The overall movement of the water will be into the cell from the solution present outside.
Explanation of Solution
Explanation/Justification for the correct answer:
Option (d) is given that when the cell is kept in a hypotonic solution, the water will flow inside the cell as well as out of the cell. The net movement of the water will be into the cell. The cell kept in the hypotonic solution will cause movement of H2O (water) in both directions; however, the water will move more from a higher H2O concentration to a lower water concentration to achieve equilibrium. Hence, Option (d) is correct.
Explanation for incorrect answer:
Option (a) is given that when the cell is kept in a hypotonic solution, the water will only flow into the cell. In this case, the cell will burst due to excess amount of solvent inside the cell. Thus, to prevent this, the water will flow out also after equilibrium state. So, it is a wrong answer.
Option (b) is given that when a cell is kept in a hypotonic solution, the water will only flow out of the cell. The solvent molecules always move from their higher concentration region to their lower concentration region. The water will flow inside instead of outside the cell, as the concentration of solvent (H2O) molecules is more in the solution. So, it is a wrong answer.
Option (c) is given that when a cell is kept in a hypotonic solution, the water will flow into the cell as well as out of the cell. The net movement of the water will be out of the cell. In this case, the cell will shrink in size and later die off. So, it is a wrong answer.
Hence, options (a), (b), and (c) are incorrect.
Thus, water will flow both into the cell and out of the cell. However, the overall movement will be inside the cell from the solution.

- In the process of exocytosis, vesicles coming from the inside of the cell fuse with the plasma membrane which travels across the membrane to be released outside the cell.
