taxonomy Flashcards
What is taxonomy
the branch of science concerned with classification, and in this context, organisms.
What is the taxonomical tree of life
It is the method by which we identify species of organisms. It is a hierachical “Tree” in which organisms are sorted on various characteristics
What charateristics can you sort organisms with?
Diet, Appearance, Behaviour, Size, Colour, Shape, Patterns and Cell (for sorting by kingdom)
What hierarchical rank is a domain
it first in hierarchical ranking. There are only 3 Domains
What hierarchical rank is a kingdom
It is second in hierarchical ranking With Domain above it and phylum below it.
What hierarchical rank is a Phylum
It is Third in hierarchical ranking With Kingdom above it and class below it.
What hierarchical rank is a Class
It is Fourth in hierarchical ranking With Phylum above it and Order below it.
What hierarchical rank is a Order
It is Fifth in hierarchical ranking With Class above it and Family below it.
What hierarchical rank is a Family
It is sixth in hierarchical ranking With Order above it and Genus below it.
What hierarchical rank is a Genus
It is seventh in hierarchical ranking With Family above it and Species below it.
What hierarchical rank is a Species
It is eighth in hierarchical ranking with genus above it aand nothing below it.
What are the charateristics of life
Move, Reproduce, Need Nutrients, Have cells, Grow, Respond to stimuli, exchange gases, Require water, Produce waste. Can use abbreviation

What are the fiove kingdosm and the difference in cell structure
Bacteria/monerans Have a nucleoid (a string of DNA) instead of of a nucleus
Protists: Have a nucleus.
Animals: Have a membrane as the cell border, Has a nucleus
Plants: Eukaryotic, have a cell wall made of Celluslose.
Fungi: have a protein cell wall
What is a dichotomious key
A dichotomous key is a tool used in biology and other fields to identify and classify organisms or objects based on their characteristics. It consists of a series of choices or questions that lead the user to the correct identification of the organism or object being studied.
The key presents a series of paired statements or descriptions, each representing a specific characteristic or trait. The user is required to select the statement that best matches the observed characteristic of the organism or object being identified. Based on their choice, they are directed to another set of statements or descriptions, further narrowing down the possibilities until they reach a final identification.
Each choice in a dichotomous key is mutually exclusive, meaning that only one statement in each pair can be true for the organism or object being examined. This process of elimination continues until the user arrives at a specific identification or classification.
Dichotomous keys are widely used in fields such as biology, botany, zoology, and ecology to identify plants, animals, insects, and other organisms. They provide a systematic and logical approach to identification and can be particularly helpful when dealing with a large number of species or objects with similar characteristics.
Why may Taxonomy change
New Species may be discovered. We discover a species has sexual dimorphirism
