Classification

Taxonomy

a field of science that identifies, classifies and name organisms

Organisms that share common ancestry are now grouped together → dolphins are more common with pumas than sharks

How to organize

  1. Domain (Dear)

  2. Kingdom (King)

  3. Phylum (Philip)

  4. Class (came)

  5. order (over)

  6. Family (for)

  7. genus (Good)

  8. Species (Soup)

3 Domains

Prokayotes

Bacteria → Eubacteria

Archaea → Archea-bacteria

Eukaryotes

Eukarya → Protista, Fungi, Plantae, Animalia

Six different Kingdoms

Eubacteria (bacteria) Kingdom

  • all prokaryotic

  • all unicellular

  • producers or consumers

  • everywhere

  • all reproduce a-sexually

Archaebacteria Kingdom

  • ancient

  • live in extreme environments → lava, etc.

Protist Kingdom

  • quite big

  • eukaryotes

  • mostly unicellular

  • producers and consumers

  • a-sexual or sexual reproduction

  • examples include algae and amoeba

  • mostly aquatic

  • any miscellaneous things are placed here

Fungus Kingdom

  • eukaryotes

  • mostly multicellular

  • examples include mold, mushrooms and yeast

  • consumers → decompose by secreting enzymes

  • a-sexual or sexual reproduction

Plant Kingdom

  • eukaryotes

  • multicellular

  • producers/autotrophs

  • photosynthesis

  • some can alternate between a-sexual and sexual reproduction

Animal Kingdom

  • eukaryotes

  • multicellular

  • consumers/heterotrophs

  • some a-sexual some sexual

  • are able to move from a to b during at least one time of their life

Invertebrates

  • sponges

  • Cnidarians → have stinging cells

    • examples include jellyfish, corals and sea anemones
