Recall Taxonomic Levels

• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species

6
Levels Greater Than Kingdoms

• These are called domains
• Remember two different types of cells
• Prokaryotes
• No nucleus
• No organelles
• Eukaryotes
• Contain nucleus
• Have organelles
• Plant vs. Animal

7
Domains

• Three Domains
• Bacteria
• Archaea
• Eukarya

8
Domain Bacteria

• Unicellular and prokaryotic
• Have thick, rigid cell walls
• Corresponds to the kingdom Eubacteria
• Contain free-living soil organisms to deadly
  parasites
• Some photosynthesize
• Some need oxygen to survive, while others are
  killed by oxygen

9
Domain Archaea

• Also unicellular and prokaryotic
• Live in volcanic hot springs, brine pools, and
  black organic mud totally devoid of oxygen (some
  of the most extreme environments)
• Many can survive only in the absence of oxygen
• Cell walls lack peptidoglycan
• Corresponds to the kingdom Archaebacteria

11
Domain Eukarya

• Consists of all organisms that have a nucleus
  (Eukaryotic)
• Organized into the four remaining kingdoms
• Protista
• Fungi
• Plantae
• Animalia

13
Six Kingdoms

• Eubacteria
• Archaebacteria
• Protista
• Fungi
• Plantae
• Animalia

14
Kingdom Protista

• Composed of eukaryotic organisms that cannot be
  classified as animals, plants, or fungi
• Members display the greatest variety

15
Kingdom Fungi

• Heterotrophs
• Most feed on dead or decaying organic matter
• These fungi secrete digestive enzymes into their
  food source then absorb the smaller food
  molecules into their bodies

16
Kingdom Plantae

• Multicellular organisms that are photosynthetic
  autotrophs
• Plants are nonmotile
• Cell walls that contain cellulose

17
Kingdom Animalia

• Multicellular and heterotrophic
• Do not have cell walls
• Most animals can move about, at least for some
  part of their life cycle
