Classification B5 Flashcards
What is the advantage of using a binomial system to name species?
It allows scientists to discuss individual species because every species has a unique name.
Which 18th Century scientist developed the traditional classification system for classifying living things?
Carl Linnaeus
Which international system is commonly used to classify organisms?
The Linean Classification System
What is the correct order of groups in the Linnaean classification system?
Kingdom, Phylem, Class, Order, Family, Genus, Species
Which two groups in the classification system are used in the binomial naming system?
Genus and species.
What is the binomial name for humans?
Homo sapiens
How do we write the binomial name of a species?
All lowercase except for the first letter of the genus and all in italics.
The binomial name for grey wolves is Canis lupus.
What are the species and genus names for the grey wolf?
The genus name is Canis and the species name is lupus.
Which 20th century scientist used microscopes and modern technology to develop the three domain system to classify organisms?
Carl Woese
Carl Woese developed the three domain system to classify organisms. What are the three domains?
Bacteria, Eukaryota and Archaea
Which of the following are considered Eukaryotes?
Plants, animals, protoctists and fungi
What do evolutionary trees show?
The evolutionary relationships (common ancestors) between the organisms being studied.
What are organisms grouped from in the binomial classification system?
Organisms are grouped from based on their characteristics such as anatomy, physiology, biochemistry and reproduction.
How do scientists gather the information for evolutionary trees?
Scientists compare the structure and DNA of different species and fossil records.
How does DNA sequencing help to classify organisms?
DNA sequencing can be used to show if organisms share common ancestors and DNA sequencing has led to some organisms being reclassified.
