An Investigation to find the Water Potential of Plant Tissue Benjamin Doughty Aim: To find the water potential of plant tissue by investigating the effects of varying concentrations of sugar solutions on the amount of osmotic activity between the solution and potato cylinders. Hypothesis: Osmosis is defined as the net movement of water from regions of high water potential to regions of low water potential. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. Prediction: Pure Water has the highest water potential (zero). For this particular investigation I think that...
