2/9/2015 Central Questions Domains and Kingdoms Different Systems • Taxonomy hasn’t always been organized the way it is today. • Linnaeus identified two Kingdoms: Plants and Animals. • More recently there were 5 kingdoms • Newer work (including our book) have 3 Domains with 6 Kingdoms • What were the kingdoms you learned in middle school? Differences in the Domains • Domain Bacteria contains the Eubacteria Kingdom. They are all unicellular prokaryotes. • Domain Archaea contains the Archaebacteria Kingdom. They are similar to Bacteria, but have different cell walls and are more related to complex life. • Domain Eukarya contains the other 4 kindgoms. It includes all eukaryotes. • What are the three domains? • What are the 6 kingdoms? • What are the major characteristics of each kingdom? Domains • Domains are the largest taxa, with kingdoms inside of them. • There are three domains, separated based on cell types. • The three domains are: –Domain Bacteria –Domain Archaea –Domain Eukarya What do you think the main difference is between Eukarya and the other two? Kingdom Eubacteria • Bacteria • Cell Type: Prokaryote • Cell Structure: Cell wall with peptidoglycan (no nucleus or membrane bound organelles) • Number of Cells: Unicellular • Nutrition: Autotroph or Heterotroph • Examples: E. coli, Streptococcus 1 2/9/2015 Kingdom Archaebacteria • Extreme Bacteria • Cell Type: Prokaryote • Cell Structure: Cell wall without peptidoglycan (no nucleus or membrane bound organelles) • Number of Cells: Unicellular • Nutrition: Autotroph or Heterotroph • Examples: Deep sea bacteria, high salt bacteria, “extreme bacteria” Kingdom Protista • Protists • Cell Type: Eukaryotes • Cell Structure: Varies, all have nuclei and organelles • Number of Cells: Unicellular, a few multicellular • Nutrition: Autotroph or Heterotroph • Examples: Ameba, paramecium, euglena Kingdom Fungi • Fungus • Cell Type: Eukaryotes • Cell Structure: Cell wall made of chitin, no chloroplasts • Number of Cells: Multicellular, some unicellular • Nutrition: Heterotroph • Examples: Mushroom, mold, yeast 2 2/9/2015 Kingdom Plantae • Plants • Cell Type: Eukaryotes • Cell Structure: Cell wall made of cellulose, have chloroplasts • Number of Cells: Multicellular • Nutrition: Autotrophs • Examples: Moss, grass, corn, trees Kingdom Animalia • Animals • Cell Type: Eukaryotes • Cell Structure: No cell walls or chloroplasts • Number of Cells: Multicellular • Nutrition: Heterotrophs • Examples: Sponges, worms, insects, fish, amphibians, reptiles, birds, mammals Central Questions • What are the three domains? • What are the 6 kingdoms? • What are the major characteristics of each kingdom? 3
