A relationship exists between electrical potential and membrane activity in plants. This electrical potential is commonly referred to as the action ("resting") potential of all cells. Action potential plays a critical role in the uptake and movement of nutrients in the plant. Resting electrical potentials between the intercellular and extracellular material of plant cells is known. Blinks, L. R., "Some Electrical Properties of Large Plant Cells," in Electrochemistry in Biology and Medicine, Shedlovsky, ed., John Wiley & Sons, New York, 1955, pp. 187-212. The resting potential can range from approximately 10-200 millivolts and may be partly responsible for active transport in plants.
