2.53 Uptake of water

Explain how water is absorbed by root hair cells.
-Branching patterns of roots increases surface area- increases absorption of water.
-End of roots have root hairs which are epidermal cells (cells on surface of root)- increases surface area, more water is absorbed.
-Active transport of minerals encourages the plant to take up water by osmosis. (osmosis- water moves from dilute to concentrated region)
-Dilute region is the soil water surrounding the root hairs and the concentrated region is created by building up the minerals in the cell by active transport.
-Water moves across the cortex of the root to the xylem by osmosis.
