Life: 3 Domains, 5 or 6 KingdomsBiology Honors
3 Domains
•Broadest, most inclusive taxon•Organized evolutionarily
▫Type of cell, # of cells, how they get energy
Domain Archaea & Domain Eubacteria•Contain all unicellular prokaryotes
▫No nucleus or membrane-bound organelles▫Division is based on cell wall components
Domain Eurkarya•More complex •Have a nucleus
and membrane-bound organelles
•Evolved through endosymbiosis?▫Evidence:
mitochondria and chloroplasts have own DNA
Domain Eukarya is Divided into Kingdoms
• Kingdoms are more specific than domains
• 5 or 6 kingdoms of classification
• Depends on how you classify prokaryotes:▫5 kingdoms: all bacteria
are in Kingdom Monera▫6 kingdoms: bacteria are
split into Kingdom Archaebacteria and Kingdom Eubacteria
Kingdom Archaebacteria•Prokaryotes•Unicellular•Heterotrophs•May represent the first cells to have
evolved
Kingdom Eubacteria•Prokaryotes•Unicellular•Heterotrophs or autotrophs•Present in almost all habitats on earth.
Kingdom Protista
•Eukaryotes•Unicellular (few multi-cellular algae)•Heterotrophs or autotrophs•Example:
▫Euglena▫Diatoms
Kingdom Fungi
•Eukaryotes•Mostly multicellular
(yeast are unicellular)•Heterotrophs•Examples:
▫Mushrooms▫Molds▫Yeasts▫Mildew
Kingdom Plantae
•Eukaryotes•Multicellular•Autotrophic •Examples:
▫Nonvascular▫Vascular
Kingdom Animalia
•Eukaryotes•Multicellular•Heterotrophs•Have mobility (except adult sponges)•No cell wall•Example:
▫Invertebrate▫Vertebrate
