Reasons why living organisms need to be classified
|
- A universal language for scientists in every country to communicate. -Identify and understand how closely related organisms are. -Identify harmful or beneficial organisms. |
|
|
Features that can be used to classify organisms
|
- Physical structure (bones.) -Their biochemistry (blood proteins.) -Development and reproduction (sexual or asexual) -Behaviour, habitat, food sources. (terrestrial or aquatic) -Their cell structure (prokaryotic or eukaryotic) -Their chromosomes number and shape. |

7 levels of Linnaean classification
|
Kingdom, phylum, class, order, family, genus, species
|
|
|
What is binomial nomenclature?
|
The scientific naming of organisms that consist of two names, the first being the genus names and the second being the species name.
|
|
|
Why scientific names are used instead of common names.
|
-Common names may vary from language to language. Such as a cat is Felis Catus all over the world but the common name cat varies from language to language. -Common names may be misleading, suggesting relationships that are not valid. For example seahorses are not horses and cuttlefish are not fish. |
|
|
If two species have the same species name, are they closely related?
|
A different genus name means they are not closely related as for an organism to be closely related they need all levels of classification for genus and above to be the same.
|
|
|
What is the definition of a species?
|
Organisms with similar features that are able to interbreed to produce fertile offspring.
