taxonomy test Flashcards
what is taxonomy?
finding,describing,classifying and naming organisms into 7 different category
what are the 7 organizations of taxon
kingdom kinky phylum people class can order only family find genus good species sex
what is the most specific taxon
species
what are the 3 domains
archaea, bacteria and eukarya
what are the 6 kingdoms
eubacteria, archaebacteria,protista, fungi,plantae and animalia
example of eubacteria
bacteria species, e. coli, salmonella, ebola
example of archaebacteria
halobater, thermacoccus
example of protista
diatoms, multicellular algae, paramecium
example of fungi
mushrooms, yeast, toadstools, mould
example of plantae
trees,flowers, grass
example of animalia
mammals, reptiles, amphibians, invertebrates
describe eubacteria
- prokaryotic and unicellular
- can be harmful or beneficial
- no membrane bound organelles
describe archaebacteria
- prokaryotic and unicellular
- no membrane bound organelles
- live in extreme environments (like volcanic vents or very salty environments)
describe protista
- eukaryotic and unicellular
- some have characteristics of plants or animals and fungi
- move using flagella, cilia or pseudopuds
describe fungi
- eukaryotic and multicellular
- have cell wall with chitin
- spread through spores
- 3 categories
describe plantae
- eukaryotic and multicellular
- cell walls have chloroplasts
- use photosynthesis
- reproduced via seeds or spores
- require co2,o2,water,nutrients and sunlight
describe animalia
- eukaryotic and multicellular
- no cell walls
- heterotrophic
- generally motile except some invertebrates
what is binomial nomenclature
combination of using a genius and species name when referring to a specific species
what is the format for binomial nomenclature
Genius is capitalized and the species is all lowercase both words are in italics or underlined if handwritten
what is the phylogenetic tree
branching diagram showing the evolutionary history of organisms
how does the phylogenetic tree work
The distance between each branch indicates the distance each species is from a common ancestor
what is a clade
A group of organisms that includes all of the descendants of a common ancestor - used in cladogram
what is dichotomous key
used to identify different organisms based on the organisms observable traits
how does the dichotomous key work
it consists of a series of statements with two choices in each step that will lead to the correct identification
what is the domain based on
Evolution according to molecular genetics
what is the kingdom’s based on
Evolution according to morphology
which thing is based on the type of RNA in the organisms
domains
what is the classification system of taxons name
Linnaeus
what is the cladogram
diagram to show the relationship between groups of organisms
