Water potential is the highest (i.e., least negative)

Question

Quizplus · Accepted Answer

Water potential is the potential energy of water to move from one place to another. It is determined by factors like solute concentration, pressure, and gravity. In plants, water moves from the roots to the leaves via the xylem. The water potential is highest (i.e., least negative) in the roots, where the solute concentration is lowest compared to the soil solution. As water moves up the xylem, the solute concentration and the pressure decrease, making the water potential more negative. Therefore, the xylem in the roots has the highest water potential.
