Bellwork: January 27 Copy and define the following words. – They’re: __________________________ – Their: ____________________________ – There: ____________________________

Happy Monday! Bellwork: January 27 Complete the questions on your Cladogram Practice worksheet from Friday!

CO: I will define taxonomy, recognize the importance of a taxonomic system, and categorize organisms into domains. LO: I will write notes. I will sort organisms with a partner. I will collect bacteria with a partner.

Classification is the grouping of objects or information based on similarities.

Taxonomy is the science of grouping and naming organisms. In other words, taxonomy is the process of classifying and naming biological (living) organisms. In Biology:

7 Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Most Specific copyright cmassengale The major classification levels, from most general to most specific A group at any level is a taxon.

Let’s look at some animals

Devil Cat

Ghost Cat

Mountain Lion

Screaming Cat

Puma

Florida Panther

Cougar

There are at least 50 common names for the animal shown on the previous 7 slides. Common names vary according to region. How could we fix this problem?

Taxonomists give a unique scientific name to each species they know about whether it’s alive today or extinct. The scientific name comes from one of two “dead” languages – Latin or ancient Greek.

The genus name is written first (always Capitalized). The species name is written second (never capitalized). Both words are italicized if typed or underlined if hand written. Example: Felis concolor or F. concolor Which is the genus? The species? Binomial Nomenclature a two name system for writing scientific names. Turdus migratorius Turdus migratorius a

21 Binomial Nomenclature Which TWO are more closely related? copyright cmassengale

Now that you know why we need to classify organisms and how to name them; we are going to learn about each taxon in detail.

23 Broadest, most inclusive taxonBroadest, most inclusive taxon Include:Include: 1.Archaea (unicellular prokaryotes) 2.Bacteria (unicellular prokaryotes) 3.Eukarya (eukaryotes) Domains copyright cmassengale

Prokaryotes Eukaryotes

25 ARCHAEA Kingdom - ARCHAEBACTERIA Probably the 1 st cells to evolve Live in HARSH environments Found in: –Sewage Treatment Plants (Methanogens) –Thermal or Volcanic Vents (Thermophiles) –Hot Springs or Geysers that are acid –Very salty water (Dead Sea; Great Salt Lake) - Halophiles copyright cmassengale

26 ARCHAEAN copyright cmassengale

27 BACTERIA Kingdom - EUBACTERIA Some may cause DISEASE Found in ALL HABITATS except harsh ones Important decomposers for environment Commercially important in making cottage cheese, yogurt, buttermilk, etc. copyright cmassengale

28 Live in the intestines of animals copyright cmassengale

29 Eukarya… is Divided into Kingdoms Protista (protozoans, algae…)Protista (protozoans, algae…) Fungi (mushrooms, yeasts …)Fungi (mushrooms, yeasts …) Plantae (multicellular plants)Plantae (multicellular plants) Animalia (multicellular animals)Animalia (multicellular animals) copyright cmassengale
