Diffusion occurs because. • molecules are attracted to one another. • molecules constantly move and collide with each other. • cellular energy forces molecules to collide with each other. • cellular energy pumps molecules across the cell membrane.

If a more-concentrated salt solution is on one side of a membrane and a less-concentrated solution is on the other side, water molecules tend to pass through the membrane • from the more-concentrated to the less-concentrated solution. • until the cell membrane is broken down. • from the less-concentrated to the more-concentrated solution. • equally in both directions.
