AS Biology coursework Investigating the water potential inside a potato chip Introduction In the experiment I will be trying to find the water potential inside a potato cell. Plants absorb water for photosynthesis by the process of osmosis. Water moves in and out of the cell by the process of osmosis through a partially permeable membrane. Osmosis by definition is the "diffusion of water only, It is the net movement of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane". "We call the overall tendancy of a cell or system to gain or lose water as water potential"- (taken from Collins AS Biology- Mike Boyle and Katharyn Senior). In terms of Water potential (?), water will always osmose "from a region of higher water potential to a region of lower water potential through a partially permeable membran"-Cambridge Biology 1 AS-...
