2. Classification
Binomial Nomenclature: each species is assigned a two-part scientific name (Genus and Species names)

4. Order

10. Classification
Members of the same species can interbreed and produce fertile offspring

11. The Kingdoms
Archebacteria – more extreme environments; prokaryotic; unicellular
Ex. Volcanic hot springs
Eubacteria – more general diversity; prokaryotic, unicellular
*bacteria are difficult to classify, evol. relationships unclear, don’t fossilize well

12. Kingdom Protista unicellular/mulitcellular eukaryotic
cells not specialized
autotrophs/ heterotrophs
ex. amoeba, algae, kelp,
slime molds, paramecium

13. Kingdom Fungi eukaryotic Multicellular/uni have cell walls
Yeast
Mildew
eukaryotic
Multicellular/uni
have cell walls
heterotrophs - release digestive enzymes onto a food source and absorb nutrients
ex. molds, mildews, yeast
Club Fungi

14. Kingdom Plantae eukaryotic multicellular have cell walls
autotrophs (most)
Mosses, ferns, flowering plants

15. Kingdom Animalia eukaryotic no cell walls Heterotrophs Multicellular
ex. sponges, insects, tigers
