semipermeable. This means only certain materials will be allowed to enter and exit through the egg’s membrane. The purpose of this experiment is study the process in which water molecules pass the egg membrane‚ osmosis. This experiment also gives insight on how other ‘semipermeable membranes’ work‚ like a model for other membranes similar. If 3 eggs are immersed in 3 different solutions- salt‚ sugar‚ & tap water- then the membrane of the egg will conduct osmosis of water into the eggs. Materials ●

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound
