Pathway Taken by Water (Cambridge (CIE) IGCSE Co-ordinated Sciences (Double Award)): Revision Note

Pathway Taken by Water

• Osmosis causes water to pass into the root hair cells, through the root cortex and into the xylem vessels:

• Once the water gets into the xylem, it is carried up to the leaves where it enters mesophyll cells

• So the pathway is:

root hair cell → root cortex cells → xylem → leaf mesophyll cells
