Unit 11 Taxonomy Flashcards
Taxonomy
Identification and classification of organisms
What Greek philosopher grouped animals into land dwellers, water dwellers, and air dwellers and classified plants into 3 categories on the basis of their what
Aristotle, stems
Who devised the 2 name system of naming organisms
Linnaeus
The domains of 3 domain system of classification are what
Archaea, Eubacteria, Eukarya
Phylogeny
Evolutionary history of a species
All scientific names are made up of 2 words that are often derived from what language
Latin
The first word of a scientific name is the what to which the organism belongs
Genus
Poison Ivy is Alison known as Rhus toxicodendron. It’s species identifier is
Toxicodendron
Two organisms in the same class but different orders will be in the same what
Phylum
Most multicellular uncleared autotrophs that carry on photosynthesis belong to what kingdom
Plantae
Most cellular uncleared heterotrophs that always obtain food by absorbing nutrients from the environment belong to what kingdom
Fungi
Archaebacteria
Simple non uncleared organisms that use hydrogen to produce methane
The more classification categories 2 species share the more what they have in common
Characteristics
A genus is subdivided into smaller groups called
Species
Kingdom
Largest category
Species
Smallest category: only one organism
Phylum
Largest subset with animal kingdom
Division
Largest subset with plant kingdom
Species name
2 part scientific name
Species identifier
2nd part of an organisms name
Varieties
Plants belonging to same species with slight differences
Subspecies
Animals belonging to the same species but different area
The main criterion used in Linnaeus system in classification
Morphology
Order
Each subset within a class of an organism
Archaebacteria
Prokaryote/ unicellular/ auto and hetero
Eubacteria
Prokaryotes/uni/hetero and auto
Protista
Eukaryotes/ multi and uni/ auto and hetero
Fungi
Eukaryotes/multi and uni/ auto and hetero
Plantae
Eukaryotes/multi/ auto
Animalia
Eukaryotes/multi/hetero
Organism that lives in hostile environment that cannot support other life forms are from what kingdom
Archaebacteria
Amoebas and giant kelp are apart of what kingdom
Protista
Fungi examples
Mushroom, puffballs, mildew, and mold
Bacteria examples (causes)
Cause tooth decay and food poisoning
Animalia examples
Organisms with true nuclei and membrane bound organelles
Eukarya includes
Protista, fungi, plants, and animals
Difference between archaebacteria and eubacteria
Archaebacteria can live in harsh environments
Difference between fungi and plants
Fungi: heterotrophs
Plants: autotrophs
Kingdom with multicellular hetero tropics organisms
Animalia and Fungi
