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

Page 4: Life: 3 Domains, 5 or 6 Kingdoms Biology Honors. 3 Domains Broadest, most inclusive taxon Organized evolutionarily ▫Type of cell, # of cells, how they.

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
