Investigation into factors that affect Osmosis in potatoes I will investigate how different concentrations of sucrose affect potato in terms of turgidity. The sucrose will be in varying concentrations compared to water. I hypothesise that the higher the concentration of sucrose around the potato, the more mass the potato will lose. I believe that this will happen as the potato will try to lose water to equalise the concentration of the sucrose compared to water, this is the process of osmosis. This happens through the pores on the selectively permeable membrane on the potato, which allows water through it but not sucrose. To measure the effect of osmosis with sucrose on potatoes, I will measure percentage change in both length and mass, using balances and measuring implements. I will measure weight to 2 decimal places, and length to the nearest millimetre. I will follow normal laboratory procedure, and will take special precautions when...
