6 KINGDOMSUnit 2 - Biodiversity
It’s Alive! What qualities distinguish something as
“living”? It can….
Grow and developReproduceObtain and use materials and energyRespond to their environmentChange over timeAre based on a universal genetic code
Are made up of units called cells
How are these living things organized?
Kingdom Phylum
ClassOrder
FamilyGenus
Species
How are organisms classified at the Kingdom Level?
Number of cells Unicellular or Multicellular
Mode of Nutrition Autotrophic or Heterotrophic
Type of cells Prokaryotic or Eukaryotic
Cell wall structure Are they there? If they are what are they made of?
Number of Cells
Made up of one cell Made up of 2 or more cells.
Unicellular Multicellular
Mode of Nutrition
Make their own food/energy
Get energy from other organisms
Autotrophic Heterotrophic
Cell Type
No nucleus or membrane bound organelles
Has a nucleus and membrane bound organelles
Prokaryotic (BACTERIA ONLY!!) Eukaryotic
Cell Walls
Peptidoglycan (some bacteria)
Cellulose (plants, some protist)
Chitin (fungi)
All Animals Some protist
Some have cell walls with… Some don’t have cell walls…
Kingdom Archabacteria Prokaryotic Unicellular Cell walls without
Peptidoglycan Some
autotrophic, some heterotrohpic
Found in harsh, extreme environments
Kingdom Eubacteria Prokaryotic Unicellular Cell walls with
Peptidoglycan Some
autotrophic, some heterotrohpic
Found everywhere! (wash your hands!)
Kingdom Protista Eukaryotic Unicellular &
Multicellular Some with cell
walls with cellulose, some without
Some autotrophic, some heterotrohpic
Mostly aquatic
Kingdom Fungi Eukaryotic mostly
Multicellular, some unicellular
Cell walls with chitin
Heterotrohpic Mostly terrestrial
Kingdom Plantae Eukaryotic all Multicellular Cell walls with
cellulose Autotrophic Terrestrial and
aquatic
Kingdom Animalia Eukaryotic all Multicellular No cell walls Heterotrophic Terrestrial and
aquatic
Let’s Review
What are the determinant criteria for Kingdoms? ___________________________
(unicellular vs. multicellular) ___________________________
(prokaryotic vs. eukaryotic) ___________________________
(composition of cell wall vs. no cell wall) ___________________________
(autotrophic vs. heterotrophic)
