Diffusion & Osmosis

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What happens during osmosis?

Back

Water moves from high to low concentration.

Front

What is the diffusion of water through a semi-permeable membrane called?

Back

Osmosis.

Front

Why is a cell considered hypertonic or shrunken?

Back

Water has rushed out of the blood cell.

Front

Why is a red blood cell considered hypotonic?

Back

The osmotic direction of water is greater entering the cell.

Front

Define Diffusion.

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the role of water in osmosis?

Back

Water moves to balance solute concentrations on either side of a membrane.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.
