The Six Kingdoms Life Science

Introduction Six Kingdoms -organized according to type of cells, ability to make food, number of cells in body Archaebacteria Eubacteria Protists Fungi Plants Animals

Terminology Getting food autotrophs – make own food hetertrophs – get food from other sources Type of cells prokaryotic – no nucleus eukaryotic – with a nucleus

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” -existed before dinosaurs -live in extreme environments -hot springs -acidic environment -methane -unicellular prokaryotes -some autotrophs, some heterotrophs

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

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

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

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

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