What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane from an area of low concentration to an area of high concentration.

Front

True or false: Water always moves from the hypotonic solution to the hypertonic solution.

Back

True.

What regulates what enters and leaves a cell?

Back

Cell Membrane.

Front

In which type of solution should your cells ideally be?

Back

Isotonic.

Front

What are the two forms of passive transport?

Back

Diffusion and osmosis.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to another solution.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to another solution.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and may shrivel.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain molecules to pass through while blocking others.
