    eInvestigating water potential of swede The aim of our experiment was to investigate the water potential of swede and then use our results to help us determine the water potential of plant tissue. This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become
