one result of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one

Effect of Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg

different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house. Osmosis is a vital mechanism in the transport of
