Plant Diversity 1

 
 

Kingdoms

  1. Bacteria -simple, single-celled organisms (Archaea, Eubacteria)

  2. Animals - complex, mostly mobile, mostly sexual reproduction, nourishment through predation (humans, horses, worms, birds)

  3. Fungi - often multicellular, non-mobile, nourishment from other organisms, can be pathogens (yeast, mold, mushrooms, c.f. lichen)

  4. Plants - often multi-cellular, non-mobile, nourishment through photosynthesis meaning they make sugar using solar energy, giving out oxygen (reproduction sexual or asexual)

  5. Virus - not truly alive, but close


Higher plants

  1. c.f. primitive spore-bearing plants (liverwort, moss, algae, horsetails, ferns)

  2. Seed plants (true seeds)

  3. Split between gymnosperms (naked seed) and angiosperms (closed seed)

    • Gymnosperms: (~840; pine, larch, spruce, juniper, yew, cycad, gingko)

    • Angiosperms: (>295,000; pea, daisy, rose, mint)

  4. Gymnosperms Lifecycle:

    • Woody

    • Perennial

    • Mostly evergreen

  5. G. Seed protection:

    • Partial or absent (pine cones are open)

  6. G. Pollination:

    • Wind (rarely also animal)

  7. G. Flowers:

    • None (basic cones)

  8. G. Resin

    • Often with piney smell

  9. G. Water transport

    • Primitive tracheids

  10. Angiosperms Lifecycle:

    • Woody or herbaceous

    • Evergreen or deciduous

    • Many types

  11. A. Seed protection

    • Complete - seeds enclosed in sealed fruit

  12. A. Pollination:

    • Wind

    • Animal

    • Water

  13. A. Flowers:

    • Complex

  14. A. Resin

    • Very rarely

  15. A. Water transport

    • Primitive tracheids

    • Advanced vessels
