Osmosis and Diffusion

Front

What is osmosis?

Back

The movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is diffusion?

Back

The process by which molecules move from an area of high concentration to an area of low concentration.

Front

What is a hypotonic solution?

Back

A solution that has a lower concentration of solutes compared to another solution, causing cells to swell.

Front

What is a hypertonic solution?

Back

A solution that has a higher concentration of solutes compared to another solution, causing cells to shrink.

Front

What is an isotonic solution?

Back

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What happens to cells in a hypertonic solution?

Back

Cells lose water and shrink.

Front

What happens to cells in a hypotonic solution?

Back

Cells gain water and may swell or burst.

Front

What is a solute?

Back

A substance that is dissolved in a solution.

Front

What is a solvent?

Back

The substance in which a solute is dissolved to form a solution.

Front

What is concentration gradient?

Back

The difference in concentration of a substance across a space.
