    • Fibrous root system
    • Reach a greater surface area
    • Tap Root system
    • good for anchoring plant. not so great for surface area.
    • Terminal bud
    • Dominant bud at the end/on top of the stem
  1. The space or portion of the stem that connect the leaf to the major stem of the plant
  2. A bud that occurs between the axil of the stem and a leaf of the plant. can become mitotically active producing a new shoot
  3. Node
    The part of the stem where leaves or new shoots originate
  4. Internode
    The part of the stem that lies between the nodes
    • Monocot Stem
    • Zea (corn)
    • Dicot Stem
    • Sunflower
    • Dicot Root
    • buttercup plant
    • Monocot Root
    • greenbriar plant
  5. Stomata
    Openings on the leafs surface that allows gases to flow in and out of it during respiration and photosynthesis
  6. Guard cells
    surround the stoma and control the opening and closing of the stoma based on the internal characteristics of the plant
  7. What are the 3 organs?
    • Stem
    • Roots
    • Leaves
  8. Function of Stems
    • 1. they support the structure of the shoot system
    • 2. they transport substances between the roots and leaves
    • 3. green stems produce food by photosynthesis
    • 4. they act as food and water storage sites

    Vascular- ploem and xylem
  9. Function of Leaves
    they produce food and have systems that regulate the respiration and photosynthesis of plants
  10. Function of Roots
    what system?
    • 1. anchor plant into the soil
    • 2. absorb water and minerals
    • 3. transport water and minerals into the shoot
    • 4. they store food for the plant

    Shoot system.
  11. Difference between primary growth and secondary growth
    • primary growth is the vertical growth of the root and shoot length. The cells increase in length.
    • secondary growth is the growth of the diameter of the plant and the girth of the stem.
  12. 3 cell types
    • xylem
    • phloem
    • epidermal
