Investigating the water potential of Potato tissue Introduction In this investigation I aim to discover the water potential and solute potential of potato tissue I will accomplish this by placing potato pieces of equal size into varying concentrations of sucrose solution and examining the percentage change in mass Then I will plot my results onto a graph and work out the intercept at which the line of best fit crosses the x-axis concentration of sucrose solution This will give me the water potential of the potato tissue ie the point at which there is no increase or decrease in mass and the cell is in equilibrium Preliminary Investigation Introduction I have conducted a preliminary investigation to examine the mass change of potato chips in 5 different sucrose solutions This will give me first hand research to help base my Hypothesis IT would also inform me in terms of which Sucrose concentrations to use in my main investigation and I can alter any variables accordingly if any problems occur with the ones I am using ie Potato strip size amount of different concentrations volume of concentration and apparatus used Apparatus Apparatus One potato One set of cork borers Two syringes Six test tubes A test tube rack A ceramic cutting tile A sharp cutting knife Distilled water Sucrose concentration 1 Mole A balance to measure mass A stop watch Notes The cork borers insure that the surface area of each potato strip is kept as standard as possible and the width is exactly the same The ceramic cutting tile prevents the underlying surface from getting damaged and a ruler ca be used to cut the potato strips for more accuracy Method Using the number 5 cork borer from the set cut out 5 strips of potato from the same potato to ensure a
