Warm Up •Friday, March 1, 2013 •State the 3 parts of the cell theory. Latin Root Quiz #3 Words Quiz: Next Wednesday, March 6, 2013 Objectives 1) Define the term taxonomy 2) Categorize real world organisms using the hierarchical classification system. 3) Compare & contrast the kingdoms Eubacteria and Archaebacteria. CLASSIFICATION & TAXONOMY NOTES Classification •Used to: 1) Name Organisms 2) Group organisms in logical order •Quick Write: Answer the following in your notes: • Why do we need a standard system for naming things? Taxonomy = scientists classify organisms & assign each organism a universally accepted name • Father of Taxonomy = Carolus Linnaeus • Developed binomial nomenclature Taxonomy •Binomial Nomenclature = each species assigned two-part scientific name •Rules: 1) Always written in ITALICS 2) 1st letter of 1st word Capitalized (Genus) 3) 2nd word all lower case (species) 4) 1st word = genus 5) 2nd word = species 6) Always in Latin •Example: Homo sapien Hierarchial System •Taxon = each level in system •Kingdom -> Phylum -> Class -> Order -> Family -> Genus -> Species •Remember: King Phillip Came Over For Good Soup Phylogeny = study of evolutionary relationships among organisms •Used to develop a classification system •AKA cladogram 3 Domains & 6 Kingdoms •Bacteria • Kingdom: Eubacteria •Archae • Kingdom: Archaebacteria •Eukarya • Kingdoms: Protista, Fungi, Plantae, Animalia Domain Bacteria •Only kingdom = Eubacteria •Characteristics: • Unicellular • Prokaryotic • Thick rigid cell wall • Contain peptidoglycan •2 Types Oxygen Needs: • Aerobes = need oxygen • Anaerobes = do NOT need oxygen • Latin Roots: a/an = not, without Domain Archae •Only kingdom = Archaebacteria • Characteristics: • Unicellular • Prokaryotic • Live in extreme environments • Examples: volcanic hot springs • Cell walls lack peptidoglycan •Most Anaerobes Prokaryotic Cells REVIEW •Only bacteria cells •Do NOT have nucleus •DNA found in cytoplasm •Do NOT have membrane bound organelles •More simple cells Eubacteria vs Archaebacteria Venn Diagram Eubacteria Both Archaebacteria Eubacteria vs Archaebacteria Table Eubacteria Domain Archae Domain Bacteria Unicellular Prokaryotic Cell well with peptidoglycan Aerobic anaerobic Live in extreme environments Archaebacteria Domain Foldables Step 1 Step 2 Step 3 Front: Make a riddle for the domain. (folds down) Bottom flap: - Draw a picture representing the domain -List 2 characteristics of domain (folds up) • When your foldable is complete, please tape or glue it to the next blank sheet in your notebook. • Title sheet “Domain Foldables” Mid flap: List domain name and associated kingdoms Classification Review Worksheet Warm Up •Monday, March 4, 2013 •What is the difference between an aerobe and an anaerobe? Warm Up •Tuesday, March 5, 2013 •List 3 characteristics of prokaryotic cells. Objectives 1) 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 Domain Eukarya •4 kingdoms = 1) 2) 3) 4) Protista Fungi Plantae Animalia •ALL are made of eukaryotic cells Eukaryotic Cells REVIEW •More complex •Have Nucleus •DNA found in nucleus •Have membrane bound organelles •Animal, plant, fungi, & protists Kingdom Protista •Eukaryotic •Great variety •Characteristics: • Most single-celled • Photosynthetic OR heterotrophic • Latin Roots: • Eu = true • Hetero = other, different • Photo = light Kingdom Fungi •Eukaryotic •Characteristics: • Heterotrophs • Most feed on dead or decaying matter • Most multicellular, but some unicellular Kingdom Plantae •Eukaryotic •Characteristics: • Multicellular • Photosynthetic autotrophs • Cells contain chloroplasts • Non-motile • Cell walls contain cellulose Kingdom Animalia •Eukaryotic •Very diverse •Characteristics • Multicellular heterotrophs • Do NOT have cell walls • Most move about during at least part of their life cycle Domain Foldables Step 1 Step 2 Step 3 Front: Make a riddle for the domain.
