Rules for Naming Organisms

The International Code for Binomial Nomenclature contains the rules for naming organisms

All names must be approved by International Naming Congresses (International Zoological Congress)

This prevents duplicated names

Slide 14

Classification Groups

Taxon ( taxa-plural) is a category into which related organisms are placed

There is a hierarchy of groups (taxa) from broadest to most specific

Domain, Kingdom, Phylum, Class, Order, Family, Genus, species

Domains

Broadest, most inclusive taxon

Three domains

Archaea and Bacteria are unicellular prokaryotes (no nucleus or membrane-bound organelles)

Eukarya are more complex and have a nucleus and membrane-bound organelles

Slide 19

ARCHAEA

Kingdom - ARCHAEBACTERIA

Probably the 1st cells to evolve

Live in HARSH environments

Found in:

Sewage Treatment Plants (Methanogens)

Thermal or Volcanic Vents (Thermophiles)

Hot Springs or Geysers that are acid

Very salty water (Dead Sea; Great Salt Lake) - Halophiles

Slide 20

ARCHAEAN

Slide 21

BACTERIA

Kingdom - EUBACTERIA

Some may cause DISEASE

Found in ALL HABITATS except harsh ones

Important decomposers for environment

Commercially important in making cottage cheese, yogurt, buttermilk, etc.

Slide 22

Live in the intestines of animals

Slide 23

Domain Eukarya is Divided into Kingdoms

Protista (protozoans, algae…)

Fungi (mushrooms, yeasts …)

Plantae (multicellular plants)

Animalia (multicellular animals)
