An investigation into the effect of differing water potentials on the mass or volume of potato tissue, with the final aim to discover the water potential of potato tissue. Plan The purpose of this experiment is to investigate the affect differing water potentials have on the mass or volume of potato tissue, with the final aim to discover the water potential of potato tissue. Many things need to be looked into when planning for an experiment. For this investigation the most fundamental of which is what water potential is. Water potential is a numerical representation of "the tendency of a solution to lose water" (reference Cambridge Advanced Sciences Biology 1 glossary page 258) and has the symbol ( ). Pure water has the highest water potential of zero. "Water potential is decreased by the addition of solute and increased by the application of pressure." (Reference Cambridge Biology 1) All other solutions have...
