GCSE biology coursework osmosis in potatoes Aim To investigate the effect of altering concentrations of a certain sugar solution, on the amount of osmotic activity between the solution and potato chips of a certain size. Introduction If the medium surrounding the cell has a higher water concentration than the cell, the cell will gain water by osmosis. Water molecules are free to pass across the cell membrane in both directions, but more water will come in the cell, and then will leave. The overall result is that water enters the cell. The cell is very likely to swell up. * If the medium is exactly the same water concentrations as the cell, there will be no movement of water across the cell membrane. * Water crosses the cell membrane in both directions, but the amount going in is the same as the amount going out, so there is no overall movement of water. The cell will stay...
