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
