Parts of the plant and functions

- Branching root pattern increases surface area, which speeds up the rate of absorption.

- Cell wall extends, which creates a greater surface area for more intake of water.

- Epidermal also specialised to maximise surface area, again for absorption of Water.

- Active Transport of minerals at the bottom of the root hair to the xylem.

- Osmosis - from dilute region (outside) to a concentrated region (inside where the cells are full of minerals)
