The Six KingdomsSlide2
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

Six Kingdoms in Taxonomy
organized
according to type of cells, ability to make food, number of cells in body
Archaebacteria
Eubacteria
Protists
Fungi
Plants
AnimalsSlide5
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, largerSlide6
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 parentSlide7
Archaebacteria
-”ancient bacteria”
-existed before dinosaurs
-live in extreme environments
-hot springs
-acidic environment
-methane
-unicellular prokaryotes
-some autotrophs, some heterotrophsSlide8
Extreme EnvironmentsSlide9
Eubacteria
Chemical makeup is different from that of archaebacteria.
-unicellular prokaryote
-some autotrophs, some heterotrophsSlide10

Bacteria CellSlide11Slide12
Protists
-“odds and ends” kingdom because its organisms are pretty different from one
another
-most unicellular, some multicellular
-eukaryotes
-some autotrophs, some heterotrophsSlide13
ProtozoaSlide14
A Ttypical ProtistSlide15
Fungi
-mushrooms, mold, and mildew
-most are multicellular, some (like yeast) are unicellular
-eukaryotes
-all are heterotrophs
-
eat dead or decaying organismsSlide16
FUNGISlide17
FUNGI includes:
Unicellular YeastSlide18
A Typical Fungal Cell
Fungal Cells HAVE CELL WALLS !!!!Slide19
Plants
-all plants are multicellular
-all are eukaryotes
-plants are autotrophsSlide20
Typical Animal CellSlide21
Animals
-all are multicellular
-all are eukaryotes
-all are heterotrophsSlide22

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)
