Question #43283
the lowest water potentials in the xylem are in the
A. roots hairs
B. vascular cylinders of roots
C. tracheids of the stem
D. leaves
E. lateral root
Expert's answer
Water always moves along water potential gradient, from higher to lower water potential. The water potential of pure water is 0. Soil has the highest water potential, so water moves to roots hairs, which have lower potential. Stem tracheids have lower water potential than root xylem. Xylem of leaves has the lowest water potential in the plants, as the water evaporates from leaf cell walls,
leaving the cells with a lower water potential. Thus, the correct answer is D
