  •   Study   Slideshow
  • Why is a transport system important to a multicellular organism?
    to support life in the cells
  •  15
  • Where do water and mineral salts enter a plant
    root hair / roots
  •  15
  • What two parts make the vascular bundle?
    xylem and phloem tissue
  •  15
  • What is osmosis?
    The net movement of water molecules from a region of higher concentration to a region of lower concentration THROUGH a partially permeable membrane.
  •  15
  • By which process do root hair take in water?
    osmosis
  •  15
  • What is transported by the xylem tissue?
    water and mineral salts
  •  15
  • Where does the xylem tissue transport water and mineral salts FROM and TO?
    from roots to leaves
  •  15
  • What is transported by the phloem tissue?
    food
  •  15
  • Where does the phloem transport food FROM and TO?
    from leaves to other parts of the plant

  • What is diffusion?
    The movement of molecules from a region of higher concentration to a region of lower concentration.
  •  15
  • What will eventually happen to the concentration of salt and water molecules in diffusion?
    They will have the same concentration.
  •  15
  • What does the stoma in a leaf allow to happen?
    Diffusion of gas in and out of the leaf.
