Review Game Taxonomy, Protists, Fungi and Bacteria

List the 8 levels of taxonomy classification (from largest to smallest) Domain(Dear) Kingdom(King) Phylum(Phillip) Class(Came) Order(Over) Family(For) Genus(Green) Species(Salad)

Scientific name: Oncorhynchus mykiss (rainbow trout) Genus: Species: Common name: This system is called (2 names): Oncorhynchus mykiss Rainbow trout Binomial nomenclature

Mark “E” for Eukaryote, “P” for Prokaryote Protists Fungi Bacteria E (true nucleus) P (no nucleus)

3 types of protists Heterotroph, move to get food Autotroph, most do not move, produce oxygen Heterotroph (decomposers) or mixotroph, reproduce by spores Animal-like protists (example: Amoeba) Plant-like protists (example: algae) Fungus-like protists (example: slime mold)

Fungi Thread-like filaments that form their body Group of those thread-like filaments, usually underneath the ground Examples of fungi Reproduction Nutrition Hyphae Mycelium Mold, yeast, mushrooms Spores Heterotrophs (absorption of nutrients from environment)

IMPACT OF FUNGI “The good list” Decomposers Food – Mushrooms – Yeast – cheese Medicine – antibiotics “The bad list” Disease – Plants disease: Wheat rust Corn Smut Dutch Elm – Human/animals disease: Athletes foot Dandruff Ringworm

Where do these bacteria live? What Domain do they belong to? COMMON BACTERIA Live: everywhere Domain: Bacteria/Eubacteria METHANOGENS, HALOPHILES and TERMOPHILES Live: extreme places – Methanogens: ruminants stomach – Halophiles: salty places (Dead Sea) – Termophiles: hot places (hot springs and volcanoes) Domain: Archae

3 Bacteria Shapes Cocci -> round Helical -> spiral Bacilli -> rod

Bacteria Nutrition AUTOTROPHS Photosynthesis – Energy from sunlight Chemosynthesis – Energy from chemicals HETEROTROPHS Saprobes – Feed on decaying materials Parasites – Feed off of living organisms

IMPACT OF BACTERIA “The good list” Decomposers + bioremediation Food (yogurt, cheese, etc.) Medicine (insulin) Help digestion/make vitamins Produce oxygen (autotrophs) Help plants grow “The bad list” Disease – E. coli – Tuberculosis – Strep throat – Staph and MRSA – Salmonella – others
