The Six Kingdoms
Standard: Organisms are classified into six kingdoms based
on external and internal characteristics
Introduction
Six Kingdoms
-organized according to type of cells, ability to
make food, number of cells in body, how the organism develops
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
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
