  1. domain eukarya
    • kingdom protista
    • -most diverse of the eukarya kingdoms
    • -no cell walls to cell walls to silica cell walls
    • -pseudopodia to cilia to flagella
    • -mostly asexual
    • --binary fission to budding to schizogony to intermediary meiosis
  2. 15 major phyla...we need to know 5
    • 1. rhizopoda (amoebas)
    • 2. euglenophyta (euglenoids)
    • 3. chrysophyta (diatoms)
    • 4. chlorphyta (green algae)
    • 5. ciliophora (ciliates)
  3. sexual reproduction in chlorophyta
    • zygotic life cycle
    • zygote is the only haploid
  4. kingdom plantae
    • cell wall of cellulose
    • very diverse life cycles
    • chloroplasts
    • sexual and asexual reproduction
    • source of most chemical energy on earth
  5. seed plants produce seeds
    embryonic sporophyte, nutritive tissue, and a protective coat
  6. advantages of seeds
    • development is further advanced than in spores
    • contains abundant food supply
    • protective seed coat
  7. two groups of seed plants
    • gymnosperms
    • angiosperms
  8. gymnosperms (naked seed)
    ovule is on the surface of the cone scale
  9. angiosperms (vessel seed)
    ovule is within an ovary
  10. phylum coniferophyta or pinophyta
    • gymnosperm
    • pines and spruces
    • monoecious- separate male and female parts on the same plant wind fertilized
  11. phylum cycadophyta
    • gymnosperm
    • cycads
    • dioecious- separate male and female plants
  12. phylum gingkophyta
    • gymnosperm
    • ginkgo
    • dioecious- separate male and female plants
  13. phylum gnetophyta
    • gymnosperm
    • gnetophytes
    • most similar to flowering plants
  14. phylum anthophyta or magnoliophyta (2 classes)
    • angiosperm
    • 2 classes: class monocotyledinae or liliopsida- monocots
    • class dicotyledinae or magnoliopsida- dicots
  15. angiosperms (flowering plants)
    • ovule- becomes the seed
    • ovary- becomes the fruit, usually
  16. the plant body
    meristematic tissue- zone of cell division
