Doctor Osmosis: Controller of all of the transporter proteins. Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of greater concentration of water to an area of lesser concentration of water. . . Really smelly demonstration…... Put a few drops of vanilla in a balloon. Shake the balloon, then wait about 30 seconds. Smell the outside of the balloon. What’s going on?. EVIDENCE. INFERENCE. Diffusion. Movement of particles from HIGH to LOW concentration.. Caused by a . concentration gradient . (difference in concentration).. Stops when it reaches . dynamic equilibrium. (equal amounts everywhere). . Leaving Certificate Biology. Higher Level. Selective Permeability. Cell membranes are selectively permeable meaning they can control what enters and leaves the cell. Selective permeability is controlled by proteins embedded in the cell membrane. . SIMPLE DIFFUSION. WHAT IS DIFFUSION.
