Unit 9/10 Classification Flashcards
(53 cards)
Taxonomists
- Scientists that identify and name organisms
Benefits of classifying
- Accurately/ uniformly name organisms
- Prevents misnomers
Classifying language
- Uses same language: Latin + some Greek for all names
- Latin names understood by all taxonomists
Aristotle
- 1st taxonomist
- Divided organisms into plants + animals, then subdivided by habitat
Carolus Linnaeus
- Father of Taxonomy
- Classified organisms by their structure
- Developed the modern naming system: binomial nomenclature
Binomial Nomenclature
- Two word name (Genus, species)
- Capitalize Genus not species
Standardized naming
- Italicized in print
- Underlined when writing
Taxon (Taxa-plural)
- A category into which related organisms are placed
- Hierarchy of groups/ taxa from broadest to most specific
Hierarchy- Taxonomic Groups
- Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
Did King Philip come over for great sex?
Domain definition
- The broadest, least specific, most inclusive taxon
Species definition
- Most specific taxon
3 Domains
- Archaea and Eubacteria:
Unicellular prokaryotes
(No nucleus/ membrane bound organelles). - Eukarya: More complex and have a nucleus + membrane bound organelles
Eubacteria
- Some may cause disease, and are decomposers
- LIVE ANYWHERE
- Commercially important in making dairy like cheese
What Domain’s the first to evolve?
- Eubacteria (prokaryotes found in all habitats except harsh ones)
Archaebacteria
- Live in harsh environments
- Vvv hot, acidic, salty places
Kingdoms in the Domain Eukarya
- Protista
- Fungi
- Plantae
- Animalia
Protista
- Live in moist or wet environments
- Cell walls made of cellulose
Fungi
- Multicellular except yeast
- Absorptive heterotrophs (digest food outside body then absorb it)
- Cell walls made of chitin
Plantae
- Multicellular
- Autotrophic
- Photosynthesis
- Cell walls made of cellulose
-ose
- Sugar
3 Plant Divisions
- Bryophytes
- Gymnosperm
- Angiosperm
Bryophytes
- Mosses: have no vessels for moving water to the leaves
Gymnosperm
- Conifers + pine trees: cones
Angiosperm
- All flowering plants
