2.53 root structure







- the branching pattern of roots increases the surface area which absoubtion
- the root hair is caused by the cell wall which is extended outwards
- there is an increase of surface area absorbtion of water
- the process of absorbtion: active transport of minerals from root
- plant takes up water
- water moves across coflex through the xylem
- this is the process of osmosis - dilute to concentrated
