- Figure 30.34 Which of the following statements is false? Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem. Transpiration draws water from the leaf. Water potential decreases from the roots to the top of the plant. Water enters the plants through root hairs and exits through stoma.Below is a series of pictures of a leaf (x.s.) from a eudicot, Syringa vulgaris. 40x (x.s.)
