The Six Kingdoms Original1860’s1930’s1960’s1990’s Animals Plants Fungi Plants FungiProtists Bacteria ProtistsBacteria Archaea Discussion Questions: Why where plants and animals known about for the longest time? What lead to the discovery of protists? Bacteria? Archaea?
ArchaeaBacteriaProtistaFungiPlantaeAnimalia Composed of Single Celled organisms Composed of Multi- Celled organisms
Cells less complex No nucleus No membrane bound organelles Single circular chromosome (DNA) Cells are more complex: Cells contain a nucleus Cells contain membrane bound organelles Can be multiple, linear chromosomes (DNA) ArchaeaBacteriaProtistaFungiPlantaeAnimalia Eukaryotic Prokaryotic Cell Type, Kingdoms, and domains
ProkaryotesEukaryotes ArchaeaBacteriaProtistaFungiPlantaeAnimalia But… The differences between Archaea and Bacteria are so vast, that scientists use Domains, a rank more general than Kingdom, to classify them. Eg. An apple tree and a blue whale have more in common than a bacteria and an archaea.
