2.53 Root uptake of water



-Root branches out, creating larger surface area for absorption

-Cell wall extends, thus creating more surface area for more intake of water

-At the bottom of 'root hair' active transport of minerals into the xylem

-Where outside is dilute, and inside the cell is concentrated with minerals, osmosis occurs

-Increase of minerals in cell through active transport increase the concentration which allows osmosis to take place
