Investigating the Water Potential of Root Vegetables. Introduction For my experiment I will be investigating the water potential of root vegetables. The vegetable I am going to use is turnip. I am going to use turnip because it is a uniform vegetable. This investigation is about osmosis. "Osmosis is the net movement of water molecules from an area of high water potential to an area of low water potential. This takes place through a partially permeable membrane." Water potential is the potential energy of the water molecules on either side of the partially permeable membrane to move. Where the water molecules are more concentrated the potential energy of the water molecules is higher. If a solution has a high water potential it has a higher concentration of water molecules and a lower concentration of solute molecules. The solution is said to be hypotonic. Low water potential is the opposite of this; the...
