Rules for Naming Organisms

• All names must be approved by International
  Naming Congresses (International Zoological
  Congress)
• This prevents duplicated names

3
Organizing Organisms

• There is a hierarchy of groups (taxa) from most
  general to most specific
• Domain, Kingdom, Phylum, Class, Order, Family,
  Genus, species, subspecies
• Division is used instead of Phylum when talking
  about plants

Domains

• Broadest, most generalized group
• Three domains
• 1. Archaea and 2. Eubacteria are unicellular
  prokaryotes (no nucleus or membrane-bound
  organelles)
• 3. Eukarya are more complex and have a nucleus
  and membrane-bound organelles (eukaryotic cells)

7
Domain Archaea
Domain Archaea has one Kingdom
Archeabacteria Archeabacteria live in harsh
environments and may represent the first cells to
have evolved. Sewage treatment
plants, thermal
vents, etc.
8
Domain Eubacteria

• Domain Eubacteria has one KingdomBacteria, some
  of which cause human diseases, are present in
  almost all habitats on earth.
• Many bacteria are important
  environmentally and
  commercially.

9
Domain Eukarya

• Domain Eukarya is the largest domain
• It is split into 4 Kingdoms
• Kingdom Protista
• Kingdom Fungi
• Kingdom Plantae
• Kingdom Animalia

10
KingdomProtista

• Most are unicellular
• Some are multicellular
• Some are autotrophic, while others are
  heterotrophic

11
Kingdom Fungi

• Multicellular, except yeast
• Absorptive heterotrophs (digest food
  outside their body then
  absorb it)
