Taxonomy
The science of identifying, naming and classifying species
Who is often considered the father of taxonomy
Carl Linnaeus
Period of Carl Linnaeus’s exsistence
1707-1778
Binomial system of nonmecleture
Genus speceis (italisized)
Is the genus species name the same in all languages
Yes
Advantages of Classification (2)
Identification becomes easier, allows for prediction of characteristics
What are the 8 levels of classification
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What are the three domains
Eukaryotes, Bacteria, Archaeans
What did Linnaeus considered the 3 kingdoms and what did he interpret a domain as
Modern domains are equivalent to his kingdoms, his three kingdoms were plant, animal, and mineral
What is the difference between bacteria and archeans
Bacteria are prokaryotes that live under regular conditions, archaeans are prokaryotes that thrive under extreme conditions
Do eukaryotes have histones?
Yes (histones are proteins in cell nucleus)
Do eukaryotes have introns?
Most of them do, introns are non-coding part of DNA/RNA
Ribosome structure of prokaryotes vs eukaryotes
70S for prokaryotes and 80S for eukaryotes
What is the cell wall in plants made of
cellulose
What is the cell wall of fungi made up of
Chitin
Cell membrane structure of eukaryotes
Straight chain, ester linked lipids with proteins
What are the six kingdoms
Plantae, Animalia, Fungi, Protista, Eubacteria, Archaebacteria
Which kingdoms are prokaryotic and which are eukaryotic
Plantae, Animalia, Fungi, and Protista are eukaryotic, eubacteria and archebacteria are prokaryotic
What is special about the animalia kingdom
Multicellular, eukaryotic, heterotrophic (absorbing nutrients from environment), Reproduces sexually, sensory organs
What phylum do humans belong to and what is special about it?
Chordata, all chordates have a spinal cord (vertebrates)
What class do humans belong to and what is special about it?
Mammalia, warm blooded, mammory glands (breast milk), body hair
What order do humans belong to?
Primates
What is special about primates
Sexually dimorphic (can tell male and female apart), eyes in front of head (3D vision), live on land, have thumbs and fingernails, placentals (babies develop inside mother)
What family do humans belong to, and what else is part of the family
Hominidae, Humans and 4 great apes (bonobos, chimpanzees, gorilla, orangutan)
