Biology Coursework PLAN Introduction I am doing an investigation, to find out on how varying one factor effects the rate of osmosis between potato cylinders and Sucrose solution. Osmosis is the diffusion of solvent (usually water) particles through a selectively permeable membrane from a region of high solvent concentration to a region of lower solvent concentration. Examples of Selectively permeable membranes are (a) the cell membrane, and (b) visking (dialysis) tubing. Such membranes are thought to have tiny pores that allow the rapid passage of small water particles, but restrict the passage of larger solute particles. Since the membrane is Selectively permeable, Osmosis is important in the passage of water into and out of cells and organisms, and depends on Osmotic pressure. Osmotic pressure The pressure exerted by the osmotic movement of water that can be demonstrated in an Osmometer. Water moves into the solution in the visking bag by Osmosis, causing the...
