  1. Characteristics

    - how big? 

    - group categorization?

    - age
    • a.       Largest group of plants
    •                                                                i.      300 families; 12,000 genera; 300,000 species
    • 1.       Such a large number
    • b.      Wildly successful group of plants and most widely distributed
    •                                                                i.      Almost Every ecosystem has flowering plants as the dominant plant
    • c.       Youngest plant phylum
    •                                                                i.      Hasn’t taken very long for this phylum to diversify from one end up to the equator down to the poles
  2. Structure
    - has a lot of ___

    __ structure:
    Some are __
    i. Woody trees, woody shrubs, non-woody herbaceous plants (usually,they are annuals)

    1. if theyare woodywith flowers, they are angiosperms

    2. No monocots are woody

    3. Dicots are woody

  3. What can they vary in?
    whether woody (dicots) or herbaceous (monocots)

    location (aquatic or terrestrial); epiphytes

    nutritive purposes (photosynthetic or parasitic)


    longevity (annuals, biennials, perennials)

    leaf arrangement

  4. a.       Some are __
                                                                   i.      Can __
                                                                 ii.      Can be __

    1.       Has a lot of __

    float on the surface

    completely submerged




    have a host plant

  5. Can vary in size
    •                                                                i.      Largest: eucalyptus
    • Smallest: duckweed
  6. Vary in longevity
    • annuals
    • biennials (flwoer in teh second year; then, the plant dies)
    • perennials
  7. Leaf arrangement
    There are numerous leaf arrangements

    1) alternate; the leaves are single at each node and alternate around the stem in an ascending spiral

    2) can be on opposite sides of the leaves; opposite arrangement;paired

    3) whorled: occurs when there are three or more equally spaced leaves at a node
  8. Stems
    •                                                                i.      Can be erect upright, horizontal,
    •                                                              ii.      Some are underground
    • 1.       Such as tubers
  9. Explain tubers
    • a.       Stem is very short in the tuber
    • b.      Underground structure has stem (which are roots); some have both underground and upright aerial stems

  10. True roots

    1) what do monocots have?

    2) What do dicots have?
    • Fibrous root system: roots are thesame size
    • taproot system: onemain root is bigger than the others with other lateral roots coming off of it
