Describe how plants absorb nitrate from the soil.

  • Plants absorb nitrates through root hairs using passive and active mechanism.
  • The nitrates cross the cortex of the root through the apoplast, symplast and vacuolar pathways into the xylem vessel of the root.
  • Transpiration pull translocate the nitrates up the plant in solution with water.
  • From the xylem vessels, the nitrates are conveyed to cells of the plant by passive and active mechanisms.
