5Classification 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?
6Taxonomy= scientists classify organisms & assign each organism a universally accepted nameFather of Taxonomy = Carolus LinnaeusDeveloped binomial nomenclature
7TaxonomyBinomial 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
8Hierarchial System Taxon = each level in system Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> SpeciesRemember: King Phillip Came Over For Good Soup
9Phylogeny = study of evolutionary relationships among organisms Used to develop a classification systemAKA cladogram
11Domain 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
12Domain Archae Only kingdom = Archaebacteria Characteristics: UnicellularProkaryoticLive in extreme environmentsExamples: volcanic hot springsCell walls lack peptidoglycanMost Anaerobes
13Prokaryotic Cells REVIEW Only bacteria cellsDo NOT have nucleusDNA found in cytoplasmDo NOT have membrane bound organellesMore simple cells

16Domain 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”
18Warm UpMonday, March 4, 2013What is the difference between an aerobe and an anaerobe?
19Warm UpTuesday, March 5, 2013List 3 characteristics of prokaryotic cells.
20Objectives1) 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
21Domain Eukarya 4 kingdoms = ALL are made of eukaryotic cells Protista FungiPlantaeAnimaliaALL are made of eukaryotic cells
22Eukaryotic Cells REVIEW More complexHave NucleusDNA found in nucleusHave membrane bound organellesAnimal, plant, fungi, & protists
23Kingdom Protista Eukaryotic Great variety Characteristics: Most single-celledPhotosynthetic OR heterotrophicLatin Roots:Eu = trueHetero = other, differentPhoto = light
24Kingdom Fungi Eukaryotic Characteristics: Heterotrophs Most feed on dead or decaying matterMost multicellular, but some unicellular
26Kingdom Animalia Eukaryotic Very diverse Characteristics Multicellular heterotrophsDo NOT have cell wallsMost move about during at least part of their life cycle
27Domain 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”
28Warm Up Wednesday, March 6, 2013 List one organelle found in plant cells and NOT found in animal cells AND give its function.
29Dichotomous Key Lab: Common Saltwater Fish of Galveston Bay
30Warm UpThursday, March 7, 2013What organelle helps maintain homeostasis? How?
