  • what do plant roots use to absorp water?
    root hairs
  • Leaf cells contain organelles called
    chloroplasts
  • -------is when a plant polinates itself.
    self pollination
  • occurs betweendifferent plants. It may involve not only other plants of the same species, but sometimes assistance from other species.
    cross pollination
  • what are the two main types of tubes in vascular plants
    phloem and xylem
  • what transports nutrients in the stem?
    Phloem
  • what is the is the transport of water up from the roots of the plant, though the xylem and out through the stomata
    transpiration stream
  • what type of plant transport is the movement of organic compounds both up to the top of the plant and down to the roots of the plant.
    translocation
  • Chloroplasts contain WHAT??, a green pigment that is involved in capturing or absorbing
    chlorophyll
  • The loss of water vapour from the leaves (through their stomata) is called
    transpiration
  • true or false: Roots both anchor plants and help them to obtain oxygen, water and mineral salts from the soil.
    true
  • what transports water in the stem?
    xylem
  • what plant organ acts as a transport system?
    The stem
  • give some examples of cross pollination?
    Wind pollination Animals and vectors Insect pollination Bird Pollination
  • List the four plant organs
    leaves, stems, roots and flowers
