LecturePLUS Timberlake Diffusion Movement of molecules from an area of higher concentration to an area of lower concentration. What happens when you spill milk on a table? Other examples: O2 and CO2 moving into and out of an animal cell O2 and CO2 moving into and out of a plant cell Osmosis is a special type of diffusion LecturePLUS Timberlake
