Information Osmosis is a "type of diffusion where water passes through a semi-permeable membrane from where water is in high concentration to a low concentration." A French scientist (Jean-Antoine Nollett) discovered osmosis in 1748. He discovered it by filling a pig's bladder with alcohol. This was then placed in water for several hours. The water had moved into the pig's bladder but very little alcohol had moved out. The pig's bladder was a semi-permeable membrane. The particles in a liquid are constantly moving. When small particles or water molecules meet a semi-permeable membrane they may pass through. But larger particles, like glucose cannot get through the membrane at all. If there is a high concentration of water molecules on one side of the membrane, then water molecules will pass through the membrane and the water appears to have moved through the membrane to the lower concentration. If the concentrations on both sides...
