Investigating Osmosis in Potato Cells Planning: Aim:- To investigate the effect of different concentrations of sucrose solution, on potato cells Osmosis:- Osmosis is the passage of high water concentration through a semi-permeable membrane to a region of low water concentration, i.e. the passage of water. Explanation of osmosis For osmosis to occur there must be; semi-permeable membranes are very thin layers of material (cell membranes are semi-permeable) which allow some things to pass through them but prevent other things from passing through. Cell membranes will allow small molecules like Oxygen, water, Carbon Dioxide, etc. to pass through. Cell membranes will not allow larger molecules like Sucrose, etc. to pass through. Regions of high concentrated water are either a very dilute solution of something like sucrose or pure water. In each case there is a lot of water, there is a high concentration of water. Regions of low concentrated water are a concentrated solution of something...
