Question

Discuss which pathway permits the passage of most solutes and water inside the
roots? Which pathway allows the entry of most of the water and some of the
solutes inside the root tissue? Explain how the Casparian strip creates a barrier for
substance moving through this pathway and how it is circumvented.

Answer 1

Answer:

Water first diffuses into the root hair by osmosis, it then diffuses from cell to cell or cell wall to cell wall (or any other combination of cells and cell walls) through the root cortex, where it eventually reaches the xylem. Water can move through the roots by three separate pathways: apoplast, symplast, and transmembrane (transcellular). In the apoplast pathway, water moves through the spaces between the cells and in the cells walls themselves. Casparian strips form a barrier to the apoplastic, the selectively permeable plasma membrane into the cytoplasm, rather than move along the cell wall.
