5 Classification Used to: Name Organisms Group organisms in logical orderQuick Write: Answer the following in your notes:Why do we need a standard system for naming things?
6 Taxonomy= scientists classify organisms & assign each organism a universally accepted nameFather of Taxonomy = Carolus LinnaeusDeveloped binomial nomenclature
7 TaxonomyBinomial Nomenclature = each species assigned two-part scientific nameRules:1) Always written in ITALICS2) 1st letter of 1st word Capitalized (Genus)3) 2nd word all lower case (species)4) 1st word = genus5) 2nd word = species6) Always in LatinExample: Homo sapien
8 Hierarchial System Taxon = each level in system Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> SpeciesRemember: King Phillip Came Over For Good Soup
9 Phylogeny = study of evolutionary relationships among organisms Used to develop a classification systemAKA cladogram
11 Domain Bacteria Only kingdom = Eubacteria Characteristics: UnicellularProkaryoticThick rigid cell wallContain peptidoglycan2 Types Oxygen Needs:Aerobes = need oxygenAnaerobes = do NOT need oxygenLatin Roots: a/an = not, without
12 Domain Archae Only kingdom = Archaebacteria Characteristics: UnicellularProkaryoticLive in extreme environmentsExamples: volcanic hot springsCell walls lack peptidoglycanMost Anaerobes
13 Prokaryotic Cells REVIEW Only bacteria cellsDo NOT have nucleusDNA found in cytoplasmDo NOT have membrane bound organellesMore simple cells
14 Eubacteria vs Archaebacteria Venn Diagram BothArchaebacteria
15 Eubacteria vs Archaebacteria Table Domain ArchaeDomain BacteriaUnicellularProkaryoticCell well with peptidoglycanAerobicanaerobicLive in extreme environments
16 Domain FoldablesStep 1Step 2Step 3Front:Make a riddle for the domain.(folds down)Bottom flap:- Draw a picture representing the domain-List 2 characteristics of domain (folds up)Mid flap:List domain name and associated kingdomsWhen your foldable is complete, please tape or glue it to the next blank sheet in your notebook.Title sheet “Domain Foldables”
18 Warm UpMonday, March 4, 2013What is the difference between an aerobe and an anaerobe?
19 Warm UpTuesday, March 5, 2013List 3 characteristics of prokaryotic cells.
20 Objectives1) List the 4 kingdoms that belong to the domain Eukarya. 2) List characteristics of a eukaryotic cell. 3) List real world examples of organisms that belong to the kingdoms Protista, Fungi, Plantae, and Animalia
21 Domain Eukarya 4 kingdoms = ALL are made of eukaryotic cells Protista FungiPlantaeAnimaliaALL are made of eukaryotic cells
22 Eukaryotic Cells REVIEW More complexHave NucleusDNA found in nucleusHave membrane bound organellesAnimal, plant, fungi, & protists
23 Kingdom Protista Eukaryotic Great variety Characteristics: Most single-celledPhotosynthetic OR heterotrophicLatin Roots:Eu = trueHetero = other, differentPhoto = light
24 Kingdom Fungi Eukaryotic Characteristics: Heterotrophs Most feed on dead or decaying matterMost multicellular, but some unicellular
26 Kingdom Animalia Eukaryotic Very diverse Characteristics Multicellular heterotrophsDo NOT have cell wallsMost move about during at least part of their life cycle
27 Domain FoldablesStep 1Step 2Step 3Front:Make a riddle for the domain.(folds down)Bottom flap:- Draw a picture representing the domain-List 2 characteristics of domain (folds up)Mid flap:List domain name and associated kingdomsWhen your foldable is complete, please tape or glue it to the next blank sheet in your notebook.Title sheet “Domain Foldables”
28 Warm Up Wednesday, March 6, 2013 List one organelle found in plant cells and NOT found in animal cells AND give its function.
