Students follow movement of water through a plant from the soil to the atmosphere. They calculate water potential at each of 5 locations in the soil-plant-atmosphere continuum. Students will: 1) predict the value and direction of the solute potential and pressure potiential in different parts of a plant, given information about physical conditions; and 2) calculate the water potential for soil, root cell, xylem, mesophyll cell, leaf air space, and atmosphere.
