G.c.s.e Coursework: Osmosis Aim: To investigate the effect that a varied concentration of solution has on the osmotic activity between the solution and potato cylinders. Hypothesis: Osmosis is a special type of diffusion. It occurs in plants when a weak solution is separated from a stronger one by a semi-permeable membrane, such as a cell wall. Water always flows from the weak solution to the strong one. This then dilutes the strong solution. This process is what moves water throughout the cells of the plant. The membrane has small holes, which only allow smaller molecules to pass through, such as water molecules, but blocks larger molecules, such as sugar molecules. This process continues until the molecules reaches an area of equilibrium. This means that the molecules are distributed evenly throughout the object, meaning that there is no higher or lower concentration. This water is than lost through the plants leaves as water...
