General Biology II Lab

Bacteria, Protists, Fungi


Taxonomy

Taxonomy

  • Taxonomy is changing

    • DNA technology is showing relationships previously not known

    • You will hear the term “clade” – what does that mean?

      • Clade – any taxon that consists of all the evolutionary descendants of a common ancestor

        • Identified by picking any point on a phylogenetic tree and tracing all the descendant lineages


Taxonomy1

Taxonomy

  • Binomial Nomenclature, Scientific Name

    • Genus species or Genusspecies

      • Genus is capitalized, species is lowercase

      • Italicized or underlined

      • Homo sapiensHomosapiens

      • Tursiops truncatusTursiopstruncatus

      • Callinectes sapidusCallinectessapidus


The domains

The Domains

  • Domain Bacteria – unicellular prokaryotes

    • Bacteria

    • Cyanobacteria

  • Domain Archaea – unicellular prokaryotes

    • Includes “extremophiles”

  • Domain Eukarya – eukaryotes

    • Kingdom Protista

    • Kingdom Fungi

    • Kingdom Plantae

    • Kingdom Animalia


Yes you will have to use the microscope

Yes, you will HAVE to use the Microscope!

  • Tips:

    • Start on Scanning objective, look for color

    • Center and focus

    • Move to the 10x objective

    • Center and focus

    • Move to the 40x objective

    • Center and focus

    • If necessary, move to oil immersion

      • Place drop of oil on slide and move oil lens into the oil

      • DO NOT get oil on any of the other lenses

      • Be sure to WIPE oil off of lens when done!!!!! (with lens paper!)

Domain eukarya kingdom protista changing

Domain EukaryaKingdom Protista - changing

Common name

  • Protozoa – heterotrophic, “animal-like”

  • Algae – autotrophic

    Groups:

  • Excavata – Giardia, Trichomonas, Euglena, Trypanosoma

  • Alveolates – dinoflagellates, apicomplexans (plasmodium), ciliates (paramecium)

  • Stramenophiles – oomycetes, diatoms, brown algae

  • Rhodophytes – red algae

  • Chlorophytes – green algae

  • Rhizaria – foraminiferans, radiolarians

  • Amoebozoans – plasmodial slime molds, Amoeba


  • Domain eukarya kingdom protista protozoa

    Make notecards

    Make Notecards!!!!!

    • On one side write:

      • Domain

      • Kingdom

      • Group

      • Genus

      • Characteristics

    • Know what is prokaryotic and what is eukaryotic!

    • On the other side:

    • Picture of the organism

    • On Handout

      • Domain is capitalized

      • Group is in bold print

      • Genus is underlined (# is the slide #)
