Biodiversity - Taxonomy Flashcards
What is taxonomy?
The science of classifying organisms into groups by their characteristics
Who developed the taxonomic system and when
Swedish botanist Carolus Linneaus in the 1700s
How many categories are species classified into. and what are they
8 levels which are called rank, Domain Kingdom, Phylum, Class, Order, Family, Genus, Species
What are the eight groups called
Taxa (single - taxon)
Species
Individuals that can interbreed and produce fertile offspring
the 3 evidence used for taxonomy
- Anatomical evidence
- physiological evidence
- DNA evidence
Anatomical evidence
Do the structures of the organisms look the same
physiological evidence
do the proteins and enzymes in the cells work the same
DNA evidence
how genetically closely related are the genes and the proteins they make
types of domains
Bacteria, Archaea, Eukarya
types of kingdoms in Eukarya
4 kingdoms, Protista, Fungi, Plantae, Animalia
what cell types are domains based on
Prokaryotes and Eukaryotes
what are the similarities between bacteria and archaea
both are prokaryotic cells that lack a nucleus and membrane-bound organelles and are much smaller than eukaryotic cells
what does Eukaryotes have that prokaryotes don’t
nuclear membrane since they have membrane - bound organelles
other names for bacteria kingdom
Monera or Eubacteria
