Investigation to find the water potential of a root vegetable (carrot) Introduction Water potential is the tendency of water molecules to move from one place to another. Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. I will be investigating the water potential of a carrot to find out at what concentration of salt solution (molar dm-3) equilibrium can be sustained between the net movement of water molecules in to the carrot cells, and the net movement of water molecules out of the cells, therefore finding out the water potential of the carrot, and at what concentration of salt solution the movement of water molecules ceases, and what concentration the water is at inside the carrots cells. I will need to include and explain the relevant AS knowledge demonstrated by this investigation. This includes ideas...
