  • ROOT HAIR CELLS AND TRANSPIRATION
    • ROOT HAIR CELLS
      • Covered in tiny ROOT HAIR CELLS
        • Increase teh surface area for absorption
      • Water enters by OSMOSIS
        • Solution inside the cells are more concentrated (fewer water molecules) than the water in the soil
      • Water continues to move between cells by osmosis
      • Reaches the XYLEM vessels
        • Carry it up the leaves
    • TRANSPIRATION
      • Evapouration of water from the surface of a plant
      • Water evapourates fromt he surface area inside the leaf
        • Diffuse out throught he open stomata
          • Causes more water to rise up the xylem to the leaves for the cells to use photosynthesis
