Transcript

  • 1. Transport in Plants
  • 2. Body is too large.
    Diffusion from the external environment is not an option
    Why do large organisms need a transport system?
  • 3.
  • 4. Most plants have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells.
    The vascular tissues of these plants are called xylem and phloem.
    Transport Systems
  • 5. The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant.
    Xylem
  • 6. Phloem, which is made up of living cells, carries the products of photosynthesis (organic nutrients) from the leaves to the other parts.
    Phloem
  • 7. Absorption of Water
  • 8.
  • 9. Transpiration
    Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants.
  • 10. Stomata
  • 11. Stomata
  • 12. Transpirational pull is the main force behind the movement of water through the xylem.
    Transpirational Pull
  • 13. Capillarity
  • 14. Xylem in root
    Soil particles
    Leaves
    Root hair cells
    Xylem in stem
    Transpiration
    Use the following words to prepare a flow chart showing water transport in plants

    What is the name of the process by which water travels up through a plant from the roots to the leaves?
  • 29. Glucose
    Carbon dioxide
    Minerals
    What substances, necessary for growth, do plants take in along with water?
  • 30. Diffusion
    Osmosis
    Active absorption
    Through which method does water enter plant cells?
  • 31. They are similar to human hair
    They increase surface area
    They produce toxic products
    What is special about root hair cells?
  • 32. Xylem vessels carry water from the leaves to the roots
    Xylem vessels carry water from the roots to the leaves
    Xylem vessels carry sugar from the roots to the leaves
    Which of the following statements is true of xylem?
  • 33. Phloem tubes carry food from the leaves to the storage organs
    Phloem tubes carry nitrates from the leaves to the roots
    Phloem tubes carry food from the roots to the leaves
    Which of the following statements is true of phloem tubes?
  • 34. Water travels up through plants, from the roots to the leaves, through their __________ vessels. It is pulled up the plant by two forces ________ and _________. The transpiration stream ends with water ________ from the leaves through the ________.
    (Phloem, Osmosis, Xylem, Evaporating, Suction pressure, stomata, Water, Capillarity)
