How Does The Active Transport Of Minerals Cause Water To Move Into The Roots?
The Endodermis is a layer of cells surrounding the Xylem. (Also known as the starch sheath as it contains starch granules). Covering the Endodermis is the Casparian *****.
The Endodermis uses Active Transport to move minerals into the Xylem, and water uses Osmosis.
Minerals = Active Transport
Water = Osmosis
Cells outside the Endodermis have a lower water potential than the inside, so water moves across into the Xylem.
Water moves through to the Xylem using the Apoplast pathway.
