Planning Aim: To investigate if osmosis occurs in a potato in varying concentrations of sucrose solution. The Investigation: I am investigating how different concentrations of sucrose solution can affect the mass of potato tissue. The concentrations I am going to use are; * Distilled water (0%) * 5% * 10% * 15% * 20% * 25% * 30% * 35% Background Knowledge: Osmosis is the special name used to describe the diffusion of water across a selectively permeable membrane, from a dilute solution to a more concentrated solution. In biology this usually means the diffusion of water into or out of water into or out of cells. Osmosis is just one special kind of diffusion because it is only water molecules and their movement we are considering. The water molecules move from where water is in high concentration (a weak solution) to where water is in low concentration (a strong solution). Require live cell membrane for osmosis to occur in...
