2.53: uptake of water

                                                                

  . . - -  ...Branching pattern: increase surface area for the absorption of water.

The roots will branch out to try to find water source.

....Root hairs – epidermal cells. Root hair extension of cell wall to increase surface area.




                                                                  Epidermal cell
Concentrated minerals.


Active transport of minerals.

....Osmosis- from dilute region (outside root hair) to (water) concentrate region. (Inside root hair)
Concentrated minerals inside root hair. Dilute region water and soil outside.

....Water than moves across context of root to xylem by osmosis.
