Front

What is the term for a solution that has a lower concentration of solutes compared to another solution?

Back

Hypotonic

Front

Define osmosis.

Back

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

Front

Define diffusion.

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is the role of a selectively permeable membrane in osmosis?

Back

It allows certain molecules, like water, to pass through while restricting others.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst.
