cell membrane - Answer A cell structure that controls which
substances can enter or leave the cell.
diffusion - Answer Movement of molecules from an area of higher
concentration to an area of lower concentration.
osmosis - Answer Diffusion of water through a selectively
permeable membrane
concentration - Answer A measurement of how much solute
