Transport in plants

  1. 1. Transport of Materials World of Plants Standard Grade Biology
  2. 2. Need for transport systems <ul><li>Plants need sugars and water to stay alive </li></ul>Water needs to travel from the roots to the leaves Sugars need to travel from the leaves to the rest of the plant
  3. 3. Xylem <ul><li>Hollow dead tubes </li></ul><ul><li>Water and minerals transported in an upwards direction </li></ul><ul><li>Made of lignin </li></ul><ul><li>Very strong so help support the plant </li></ul>
  4. 5. Phloem <ul><li>Transports sugar around plant </li></ul><ul><li>Made of living cells </li></ul><ul><li>Companion cells provide the energy for the tube cells. </li></ul><ul><li>The end walls of the tube cells have pores through which food is transported from cell to cell in the form of dissolved sugars </li></ul>
  5. 7. Stomata <ul><li>Tiny pores found on the surfaces of a leaf </li></ul><ul><li>Stomata take in carbon dioxide from the air through stomata </li></ul><ul><li>Water vapour passes out from the leaf to the atmosphere through stomata </li></ul>
