Emily Grant 2003 Investigation Into How Osmosis In Potatoes Is Affected By Solution Concentration PLAN Aim To investigate how the concentration of a salt and water solution affects the rate of osmosis in a potato. Osmosis Osmosis is the passage of water from an area of high water concentration to an area of lower water concentration, through a partially permeable membrane (a membrane which allows small molecules like oxygen, carbon dioxide, water, ammonia, glucose etc to pass through, but does not allow larger molecules such as sucrose, starch, protein etc). Cell membranes are partially permeable, which allows water to pass from one cell to another within the organism, and also, as I will be exploring in this investigation, from outside to inside, or vice versa. Osmosis occurs when the area of liquid outside the cell contains more water particles than the area of liquid inside the cell. In the solution, the particles are moving all the time. In...
