4) A graded potential is just the slight difference in charge across the membrane of a cell. If more negatively charged ions like potassium and sodium go across to the interior of the membrane than the inside charge becomes more negative.
Water potential is the potential pressure of water relative to pure free water (e.g. deionized water) in reference conditions. It quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects including surface tension. Water potential is measured in units of pressure and is commonly represented by the Greek letter Ï (Psi). Typically, pure water with standard temperature and pressure (or other suitable reference condition) is defined as having a water potential of 0. The addition of solutes to water lowers its potential (makes it more negative), just as the increase in pressure increases its potential (makes it more positive).
