Latin Root Quiz #3 Words Quiz: Next Wednesday, March 6, 2013

Objectives Define the term taxonomy Categorize real world organisms using the hierarchical classification system. Compare & contrast the kingdoms Eubacteria and Archaebacteria.

Classification & Taxonomy Notes

Classification Used to: Name Organisms 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 Archae Eukarya Kingdom: Eubacteria 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 Both Archaebacteria

Eubacteria vs Archaebacteria Table Domain Archae Domain Bacteria Unicellular Prokaryotic Cell well with peptidoglycan Aerobic anaerobic Live in extreme environments

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) Mid flap: List domain name and associated kingdoms When your foldable is complete, please tape or glue it to the next blank sheet in your notebook. Title sheet “Domain Foldables”

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 = ALL are made of eukaryotic cells 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. (folds down) Bottom flap: - Draw a picture representing the domain -List 2 characteristics of domain (folds up) Mid flap: List domain name and associated kingdoms When your foldable is complete, please tape or glue it to the next blank sheet in your notebook. Title sheet “Domain Foldables”
