Candidate No. 9115 Biology Investigation Lee Ramsingh Centre No. 51411 Osmosis in Potato Cells Purpose of investigation We will investigate OSMOSIS in potato cells. From this, we will analyse the turning point, where the concentration of the sucrose solution is approximately equal to the concentration of sucrose inside the potato cells. Initial Notes We have decided to use the concentration of the sucrose solution as our variable. A range of 5 different concentrations should be sufficient, and 5 repeats will be enough to give us a good average in the time allocated. Sucrose is chosen instead of glucose, because glucose molecules are smaller than sucrose molecules and is similar to water molecules. We will be given a potato and 1.0 molar sucrose solution. The different concentrations will be: 0.1, 0.2, 0.3 0.4 and 0.5 molar solution. We will have to make these different gradients by mixing the solution with water in proportion. Therefore, a 0.2 molar solution...
