2 The History of Classification In the 1700’s, Linnaeus separated all life into 2 Kingdoms: Plants and Animals. More kingdoms added as knowledge of the diversity of organisms increased. We currently have 6 Kingdoms. Remember: Kingdoms are the broadest taxon: KPCOFGS


4 Six Kingdoms in Taxonomy organized according to type of cells, ability to make food, number of cells in body 1.Archaebacteria 2.Eubacteria 3.Protists 4.Fungi 5.Plants 6.Animals

5 Terminology Getting food autotrophs – make own food hetertrophs – get food from other sources Type of cells prokaryotic – no nucleus, membrane bound organelles, DNA is circular (plasmid), do contain ribosomes, smaller eukaryotic – with a nucleus and organelles, DNA in chromosomes, larger

6 Terminology Continued Body type unicellular – made of only one cell multicellular – made of more than one cell; -have cells with special functions Reproduction sexual – need male and female parents asexual – need only one parent

7 Archaebacteria “ancient bacteria ” -first bacterial existence -live in extreme environments -hot springs -acidic environment -methane -unicellular prokaryotes -some autotrophs, some heterotrophs

8 Extreme Environments

9 Eubacteria Chemical makeup is different from that of archaebacteria. -unicellular prokaryote -some autotrophs, some heterotrophs

10 A Typical Bacteria Cell


12 Protists -“odds and ends” kingdom because its organisms are pretty different from one another -most unicellular, some multicellular -eukaryotes -some autotrophs, some heterotrophs

13 Protozoa

14 A Ttypical Protist

15 Fungi -mushrooms, mold, and mildew -most are multicellular, some (like yeast) are unicellular -eukaryotes -all are heterotrophs -eat dead or decaying organisms


17 FUNGI includes: Unicellular Yeast

18 A Typical Fungal Cell Fungal Cells HAVE CELL WALLS !!!!

19 Plants -all plants are multicellular -all are eukaryotes -plants are autotrophs

20 Typical Plant Cell

21 Animals -all are multicellular -all are eukaryotes -all are heterotrophs

22 Typical Animal Cell

23 The Six Kingdoms Review Eubacteria- “true” bacteria (prokaryotic) Archaebacteria – “ancient” bacteria (prokaryotic) Protista – WEIRD organisms!!!! (eukaryotic) Fungi – digest dead or decaying matter (eukaryotic) Plantae - stationary, photosynthetic (eukaryotic) Animalia – mobile heterotrophs (eukaryotic)
