Gcse biology osmosis Aims of the investigation: to use scientific knowledge and practical skills to determine the effect of a range of salt solutions (0.2, 0.4, 0.6, 0.8 and 1.0M plus distilled water) on living cells (potato). What factors might affect it? Length - of membrane, Temperature - of water, Concentration - of solution The factor I will change will be. The Independent variable (things you change), the thing that I will be changing in this investigation into the factors affecting osmosis, is the concentrations of the solution that helps me to investigate osmosis with potato tissues. The different sugar concentrations will be changed to see the result of the potatoes when placed in sugar solutions placed in different molarities (strengths). Planning My aim for this experiment is to see the results of potato tissue's mass difference, when placed in different concentrations of sugar solutions. Variables involved: For this experiment I would expect to have 3 different...
