Classification & Taxonomy Ch. 18
Examples of ___________
ß_________ Linnaeus - ( ) a Swedish physician who was interested in plants ßHe devised a __________ way of classifying all known kinds of organisms that we still use today.
ß b. All names in Latin c. He put together the Genus and the ________________ name d. Always written - Homo sapiens 1. Capitalize Genus Name 2. Lower case species name 3. Underline both or italicize Genus and species a. He gave each organism a __________________________ using Binomial Nomenclature - (two word name)
Why Binomial Nomenclature? England - RobinNorth America - Robin Erithacus rubiculaTurdus migratorius Scientific Names avoid ______________ -different animals with same name
Sand dollar Seahorse Scientific Names avoid confusion -___________________________
Puma, cougar, or mountain lion? Puma concolor Scientific Names avoid confusion - one animal with __________ names
Species ßTwo organisms are the same ___________ if they can breed and produce fertile offspring. Felis domesticus Puma concolor (can’t breed with other two – not same species)
Phylum Chordata ßThe most obvious characteristics of the Phylum Chordata are… 1.A dorsal, hollow nerve cord (spinal cord) 2.A notochord (_____________________) All of these organisms belong to the phylum Chordata.
Kingdom Animalia ßCharacteristics are... 1.Multicellular 2.Heterotrophic – get food from other sources 3.No __________________________ 4.Most are motile at some point in their life ßSome examples are … sponges worm jellyfish
ßKingdom ß______________ ßClass ßOrder ß________________ ßGenus ßSpecies Kingdom Phylum Class Order Family Genus Species 7 Levels of taxonomy from largest to smallest
ßEach level is called a taxon ßThe largest is the ______________ ßThe smallest (most specific) is the species ßScientific name = Genus species
ßKingdom ßPhylum ßClass ßOrder ßFamily ßGenus ßSpecies How can I remember these? Make a silly sentence… King Phillip Came Over For Great Spaghetti King Phillip Came Over For Good Soup
Domains ßNote: domain is larger than kingdom ßThe 3 domains are: ß _________________ ßArchaea ßEukarya
