Question

Explain Apoplast pathway of water in plants. Draw a diagram to show major paths of water flow in plant cells.

Answer 1

Apoplast Pathway:

Here water passes from root hair to xylem through the walls of intervening cells without crossing any membrane or cytoplasm. The path­way provides the least resistance to movement of water. However, it is interrupted by the presence of impermeable lignosuberin casparian strips in the walls of endodermal cells.
