1. Root hair cells branch out to absorb more water

2. They are adapted to this by having a large surface area, maximizing the intake of water

3. There are already minerals present (due to active transport) in the root hair cells which attracts the water

4. The water moves into the root hair cell from the soil, via diffusion.

    the minerals are concentrated in the root hair cell by active transport.

    This concentrates the cytoplams of the root hair cells now water can move by osmosis into the cell from the dilute soil water
