Read this miscellaneous essay and over 88,000 other research documents determination of the water potential of potato tuber cells determination of the water potential of potato tuber cells. Water potential is a numerical representation of how water moves from one area to another due to osmosis, gravity, or capillary action in biology it is important for understanding water movement within the environment.
- Determination of the water potential of potato tuber cells method five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes.
- The presence of solutes dissolved in water lowers the water potential obviously then, water moves from an area where the solute concentration is lower to an area where the solute concentration is higher distilled water is the purest water (highest possible ys=0 mpa) and water with dissolved salts has lower water potential (ys0, that is negative.
