    How does most of the water moves within the root?

    Answer:

                      Most of the water flow in the root occur via the apoplast pathway since, the cortical cells are loosely packed and hence offer no resistance to water movement, which is through massflow. This mass flow of water occurs due to adhesive and cohesive properties of water. However, symplast pathway is also involved in the movement of water molecules within the root (i.e., via endodermis to xylem).
