|
What is a taxon? |
A taxonomic group of any rank, such as a species, family, or class. |
|
|
Who is Carl Linneaus and what did he do? |
The Father of Taxonomy. His system for naming, ranking, and classifying organisms is still in wide use today. |
|
|
What is nomenclature? |
The devising or choosing of names for things, especially in a science or other discipline. |
|
|
What is the order of taxonomic categories? |
There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. |
|
|
What is the standard for naming new species? |
Species are considered scientifically described when they have been given a two-part Latin name and have had a description published in a peer-reviewed scientific journal. |
|
|
What is binomial nomenclature? |
The system of nomenclature in which two terms. The first one indicating the genus and the second the specific epithet. |
|
|
How is binomial nomenclature written? What language? |
Is a formal system of naming species of living things by giving each a name composed of two parts. |
|
|
What does polyphyletic mean? |
Derived from more than one common evolutionary ancestor or ancestral group and therefore not suitable for placing in the same taxon. |
|
|
How many Domains are there? |
Three domains: Archaea (a term which Woese created), Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or single-celled organisms whose cells have no nucleus. |

|
What eukaryotic organisms are autotrophic and have their own kingdom? |
Plant. |
|
|
What physical characteristics of cells separate plant and animal cells? |
Plant cells have a cell wall chloroplast and permanent vacuole unlike animals cells which do not. |
|
|
What is evolutionary systematics? |
Evolutionary classification, or Darwinian classification, and Synthetic systematics, is a way to determine natural relationships of organisms by studying a group in detail and comparing degree of similarity. |
|
|
What does homology mean? |
Similarity in sequence of a protein or nucleic acid between organisms of the same or different species. |
|
|
What does phylogeny mean? |
The branch of biology that deals with phylogenesis. |

What is a dichotomous key and what is it used for? |
Is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. |
|
|
What is a cladogram and what is it used for? |
A branching treelike diagram used to illustrate evolutionary (phylogenetic) relationships among organisms. |
|
