2.53 Root Structure
+ Root Structure has a branching pattern, this increases SURFACE AREA and the ABSORBTION OF WATER.
+ the Root has ROOT HAIR, contains of epidermal cells (surface)
+ the ROOT HAIR activly concentrates minerals, inside the root. This encourages the take of water by OSMOSIS.
+ OSMOSIS = dilute region -> concentrated region
+ water then travels from the ROOT to the XYLEM also using OSMOSIS.
