The Six Kingdoms Mrs. Feorino 7th Grade Science P.S. DuPont Middle School 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 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 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 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 Archaebacteria “ancient bacteria” -first bacterial existence -live in extreme environments -hot springs -acidic environment -methane -unicellular prokaryotes -some autotrophs, some heterotrophs Extreme Environments Eubacteria Chemical makeup is different from that of archaebacteria. -unicellular prokaryote -some autotrophs, some heterotrophs A Typical Bacteria Cell Protists -“odds and ends” kingdom because its organisms are pretty different from one another -most unicellular, some multicellular -eukaryotes -some autotrophs, some heterotrophs Protozoa A Ttypical Protist Fungi -mushrooms, mold, and mildew -most are multicellular, some (like yeast) are unicellular -eukaryotes -all are heterotrophs -eat dead or decaying organisms FUNGI FUNGI includes: Unicellular Yeast A Typical Fungal Cell Fungal Cells HAVE CELL WALLS !!!! Plants -all plants are multicellular -all are eukaryotes -plants are autotrophs Typical Plant Cell Animals -all are multicellular -all are eukaryotes -all are heterotrophs Typical Animal Cell 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)
