The Effect of Sucrose Concentration on Osmosis Aim The aim of this experiment is to find out the effect sucrose concentration has on the mass of a potato cell and the rate of osmosis. We also want to find the concentration of the cell sap in a potato. Introduction If water is withheld from a flowering plant, the flowers wilt. If bacterial cells are placed in concentrated salt water solution, they collapse and die. Human red blood cells placed in fresh water expand and burst. These are examples of the effects of osmosis, the process by which water passes through a cell membrane. Osmosis is a specific form of diffusion that only affects water molecules. It is the movement of water molecules from an area of high concentration, to an area of low concentration through a semi-permeable membrane. An example of osmosis occurs when a sugar solution and water, top, are separated by a...
