The processes of water flow in xylem and sugar translocation in phloem differ in many respects.Which of the following is not a difference between xylem and phloem transport?
A) Water potential gradients are required for xylem transport to occur,but not for phloem transport.
B) Xylem transport is a wholly passive process;phloem transport includes active (energy-requiring) processes.
C) Cells through which xylem transport occurs are "dead" at maturity;those in phloem transport are "alive."
D) Xylem transport always occurs in the same direction;phloem transport does not.
