Main Experiment Investigating the effect of osmosis in potatoes when put in sucrose solution Aim To find out the net movement of water when potato chips are put in different concentrations of sucrose solution. Scientific Knowledge Osmosis is the process by which water molecules pass through a partially permeable membrane from an area of high concentration of water to an area of lower concentration of water (e.g. from distilled water to concentrated sucrose solution). The reason for this is because of the natural tendency of water to spread from regions of high concentration to regions of low. This spreading process is called osmosis. Several examples of osmosis can be seen in nature that can give a better idea of what is happening during osmosis. E.g. if water is withheld from a flowering plant then the plant will wilt. If bacterial cells are placed in concentrated salt-water solution, they collapse and die. Human...
