Question

Immerse a living cell in a hypotonic solution and water will tend to
Options
A diffuse into the cell
Correct Answer
B diffuse out of the cell
C show no net movement
D move in by endocytosis
Correct Answer

Option A is the correct answer.

Detailed Explanation

A hypotonic solution has a lower concentration of solutes (and thus a higher concentration of water) compared to the inside of the cell. Water moves by osmosis across a semi-permeable membrane from an area of high water concentration (the solution) to an area of low water concentration (inside the cell), causing water to diffuse into the cell.

Hint

Remember the direction of water movement: towards the higher solute concentration.
