Hypotonic solution description.

Hypotonic solution description.

• A. Isotonic Solution
• B. Hypertonic Solution
• C. Hypotonic Solution
• D. Diffusion

Answer: (C)

Tonicity describes how a solution’s solute concentration compares with that inside a cell. A hypotonic solution has a lower solute concentration outside than inside, so water moves into the cell by osmosis. This causes the cell to swell and may lead to bursting in animal cells, while plant cells become turgid because the cell wall resists bursting. An isotonic solution has equal solute on both sides, so there’s no net water movement. A hypertonic solution has higher solute outside, pulling water out and causing the cell to shrink. Diffusion is the general movement of particles from high to low concentration, not a description of how a solution affects a cell’s water balance.
