- From soil to root hair
- The water is taken in at the root hair by osmosis
- The root hair is a very thin, single-celled extension
- Thousands of them give a very large surface area
- As there is a thin layer of water covering each soil particle
- It moves into the hair because there is a lower concentration of solutes in the soil that inside the root hair cell
- The root hair is a very thin, single-celled extension
- E.G. The water potential outside the root hair cell is HIGHER than inside the cell.
- Moves from a higher water potential to a lower water potential, passively down the gradient.
