Classifying living things Flashcards
what is the binomial system
system which uses the genus name and the species name to avoid confusion naming organisms
What language does the binomial system use
Latin
Why does the binomial system work well when discussing and identifying.
avoids language barriers
The system is universal, every country uses the same name
If common names where used, when translated into another language, it may translate into something else
what is the name of the man who created domains
Carl woese
when did carl woese die
1993
what is the difference between carl woese and carl linneaus
Carl Woese- discovered domains, archaea, Eukaryotae, Eubacteria
Carl Linneaus- devised the binomial system
What are the three domains
Eukaryotae- contains nuclei
Archaea- No nuclei, primitive bacteria/ extremophiles
Eubactera- No nuclei, true bacteria
Why did carl woese decide to categorise the bacteria domains into two separate domains (Archaea and Eubacteria)
Carl discovered DNA and RNA and decided to separate the bacteria domain into
Archaea and Eubacteria
What is the order of the taxonomic heirarchy in order highest to lowest.
Domain- Eukaryote, Archaea, Eubacteria
Kingdom- Plantae, Animalia, Fungi, Protoctista, Prokaryotes
Phylum
Class
Order
Family
Genus
Species
What acronym can be used to remember the taxonomic heirarchy
Kings Play Chess On Fancy Gold Squares
what are the four reasons we group and categorise species
makes studying living things more manageable
easier to identify organisms
predict characteristics
make evolutionary links
When writing a binomial name,
How should we write it ?
Which part of the name requires capital letters?
In italics and always underline what you wrote to show its in italic.
The genus name requires an upper case letter
The species name is written in lower case
use comparative vocab
chimpanzee has smaller/shorter thumb
thicker fingers
wider wrists
longer palm
what term describes differences between two populations of the same species
intraspecific variation
If two populations of the same species have developed different characteristics, why cant you immediately classify them as two different species
- there may not be enough phenotypic differences
-if they can interbreed and produce fertile offspring they are still a species
-if they have only become slightly distinct for a short period of time, they would need to be isolated for a long time,
-they are still genetically similar
-similar cytochrome c sequence
