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)
