Question

When a cell is placed in a hypertonic solution:

• A. solute exits the cell to equalize the concentration on both sides of the membrane
• B. water exits the cell toward the area of lower solute concentration
• C. water exits the cell toward the area of higher solute concentration
• D. solute exits and water enters the cell

Answer 1

Answer: (C)

water exits the cell toward the area of higher solute concentration

A hypertonic solution is a solution which has higher osmotic pressure i.e; having more solute concentration outside the cell than inside. When a cell is placed in a hypertonic solution, the water moves to the surrounding from inside the cell as it moves from higher water concentration to lower water concentration.

So, the correct option is 'water exits and solute enters the cell'.
