6 KINGDOMS Unit 2 - Biodiversity

It’s Alive!  What qualities distinguish something as “living”?  It can…. Grow and develop Reproduce Obtain and use materials and energy Respond to their environment Change over time Are based on a universal genetic code Are made up of units called cells

How are these living things organized?  Kingdom  Phylum Class Order Family  Genus  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. UnicellularMulticellular

Mode of Nutrition  Make their own food/energy  Get energy from other organisms AutotrophicHeterotrophic

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)
