Classification

Question 1

Why do we bother classifying organisms

Answer 1

When Biologists from different countries discuss a particular organism they need to be sure they are all referring to the same one. We need an internationally recognised way of identifying different groups of organisms

Question 2

What is taxonomy

Answer 2

Taxonomy is the science of describing, classifying and naming living organisms. This includes plants, animals and microorganisms

Question 3

What is the order of the taxonomic groups

Answer 3

Domain, kingdom, phylum, class, order, family, genus and species

Question 4

What are the 3 main taxonomic groups

Answer 4

The archea, the bacteria and the eukaryota

Question 5

What is the difference between analogous features and homologous features

Answer 5

Analogous features are features that look similar or have a similar function but are not from the same biological origin whereas homologous features are structures which genuinely show common ancestry

Question 6

What is the most common definition of a species and what is its limitation

Answer 6

A species is a group of organisms with similar characteristics that interbreed to produce fertile offspring. Some of the limitations are that all of the organisms in a species cannot attempt to interbreed to produce fertile offspring because they don’t all live in the same area
