Six-Kingdom Classification

Classification



Aristotle first classified organisms as either plants or animals…. This was good until…



There are forms of life that do not fit into those categories!!!



Currently, we use the six-Kingdom classification system..



*** use to be 5, but we separated Eubacteria and Archaebacteria…Why?

The Six Kingdoms

 Archaebacteria  Eubacteria  Protista  Fungi  Plantae  Animalia

Archaebacteria

    Unicellular prokaryotes.

Do not have a nucleus Live in Harsh environments.

Reproduce Binary Fission

Eubacteria

     Unicellular Prokaryotes Do not have a nucleus The bacteria around us Can be good and bad…how???

Reproduce Binary Fission

Protista

    Most are unicellular eukaryotic Can be heterotrophic or autotrophic This is the place to put all Eukaryotes that are not plants, animals, or fungi.

Not necessarily related, but unsure where to place them

Fungi

   Multicellular Eukaryotic Heterotrophic…decomposers Over 100,000 species of fungi including fungi, mushrooms, mildews, molds.

Plantae

 Multicellular eukaryotic  Autotrophic (can make their own food…Photosythesis)  Examples include mosses, ferns, conifers, and flowering plants.

Animalia

    Multicellular Eukaryotic Heterotrophic Most animals have symmetric body organization and move about in their environment Examples: Birds, insects, worms, mammals, reptiles, and humans
