  • 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
  • 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.
