Investigation on Osmosis Introduction Since I'm doing coursework involving the process of osmosis, it would probably be useful to state what osmosis is and how it works. A definition of osmosis is the movement of water from a region of high concentration to a region of low concentration through a semi permeable membrane until the concentrations are equal. A semi permeable membrane allows certain small molecules through (such as the water above) but doesn't let larger molecules (such as the sugar above) through it. In the diagram above, the water will move from side B were there is more water to side A were there is less water. This will continue until the concentration of water molecules is equal in both solutions. I learnt this simple example in my biology lesson and used information from the "Biology for You" textbook by Gareth Williams Aim My aim is to find out how osmosis occurs in potatoes at...
