what is classification?
the process of placing living things into groups. you can place the species in a category wuth other species which have similar characteristics.
1 of 12
what is phylogeny?
study of evolutionary relationships between organisms
2 of 12
what is taxonomy?
the study of the principles of classification and the study of the differences between species.
3 of 12
what is modern classification?
this reflects the evolutionary distance between species
4 of 12
why should we classify?
to predict characteristics, easier to identify organisms, helps us to see evolutionary relationships between species, more manageable
5 of 12
how many domains and kingdoms are there?
there are three domains and six kingdoms
6 of 12
what are the three domains called?
bacteria, archea, eukarya
7 of 12
what are the rules for the binominal system?
name printed in italics, underlined or handwritten, first letter of genus is capitalised, genus comes first followed by species
8 of 12
how do you identify living things?
dichomous key, asks a series of questions, each queston has two answers, usually ''yes'' or ''no''

what did Carl Linneaeus do?
devised a scheme of classification, hierarchial classification system, categories are taxonomic groups, 5 kingdom classification in his original classification

new classification systen after studying rRNA, cell membrane lipid structure and senstitivity to antibioatives
