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.
