when molecules move from a low concentration to a high concentration 

when molecules move from a high concentration to a low concentration.

no movement 

molecules move everywhere

a large  amount of substance on  side of the cell and a small amount on the other side

a small  amount of substance on  side of the cell and a large amount on the otherside

equal amount of substance on either side of the membrane  

no particles on either side of the a cell membrane

The movement of materials across the cell membrane that requires NO ENERGY from the cell.

The movement of materials through (or across) the cell membrane

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

The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)
