Taxonomy

• Classifying living things according to their evolutionary relationships– Similarities and differences– Examples: Structure, chemistry, development,

behavior, etc.

• Uses the language Latin• Classification system developed by

Carrolus Linnaeus

Taxonomy

• Eight taxa- groupings of organisms1. Domain2. Kingdom3. Phylum4. Class5. Order6. Family7. Genus8. Species

• Dear King Phillip Came Over From Great Spain

5 Kingdom Classification

Domain Bacteria• Kingdom Monera- Unicellular and prokaryoticDomain Eukarya2. Kingdom Protista- Unicellular/multicellular and

eukaryotic3. Kingdom Fungi- Unicellular/Multicellular, eukaryotic

and decomposers4. Kingdom Plantae- Multicellular, eukaryotic and

autotrophic5. Kingdom Animalia- Multicellular, eukaryotic and

heterotrophic

6 Kingdom Classification

Domain Bacteria

1. Kingdom Eubacteria- Unicellular and prokaryotic with peptidoglycan

Domain Archaea

2. Kingdom Archaea- Unicellular and prokaryotic without peptidoglycan

Domain Eukarya

3. Kingdom Protista- Unicellular/multicellular and eukaryotic

4. Kingdom Fungi- Unicellular/Multicellular, eukaryotic and decomposers

5. Kingdom Plantae- Multicellular, eukaryotic and autotrophic

6. Kingdom Animalia- Multicellular, eukaryotic and heterotrophic

Taxonomy

• Binomial Nomenclature- System of giving every species a unique two-part scientific name– First word- Genus; capitalized– Second word- species; lower-case– Each word must be underlined in italics– Example: Panthera onca or Panthera onca

Kingdom Animalia• Heterotrophic• Mutlicellular; eukaryotic• No cell walls• Cells organize into tissues and

then into organs• Organs often organize into organ

systems• Live in water, on land and in air• Most motile (able to move); some

lack motility as adults• 2 subkingdoms: Parazoa (Porifera)

and Eumetazoa (all other phyla)
