Today’s exciting topic…. Classification of Living Organisms
PowerPoint Jeopardy Classification of Living Organisms
Organisms that are best suited to their environment will most likely survive, reproduce and pass these traits on to their offspring. This principle is known by what name? What scientist first proposed this idea?
Natural Selection Charles Darwin Back to Game Board
Who was the first person to attempt the classification of the living organisms on Earth?
Aristotle Back to Game Board
Aristotle classified all animals into what three groups? He classified all plants into what three groups?
Animals • Land dwellers • Water dwellers • Air dwellers • Plants • herbs • shrubs • trees Back to Game Board
This branch of biology classifies organisms and assigns each organism a universally accepted name.
Taxonomy Back to Game Board
This is a new system of classification that uses “shared derived characteristics” to show evolutionary relationships.
Cladistics Back to Game Board
What was the problem with the system of classification proposed by Aristotle?
Many organisms were placed in groups in which there was no relationship with the other organisms found there. Air dwellers: Birds, bats, flying squirrels, and insects would be classified together, but they are not very closely related to one another. Back to Game Board
What is the problem with using common names when classifying living organisms?
Common names are very misleading and very confusing. For example: “Starfish” are neither stars nor fish. Back to Game Board
The study of the evolutionary relationships among organisms is known as:
Phylogeny Back to Game Board
What name is given to structures that are similar in structure but different in function? Given an example.
Homologous structures The arm of a human is homologous to the wing of a bat. Back to Game Board
A structure that is reduced in size, and seems to be “left over” from a previous ancestor is called a? Give an example.
Vestigial structure Example: The human appendix Back to Game Board
What scientist was the first to attempt a scientific classification of living organisms in the 1700’s? On what did he base his system of classification?
Carolus Linnaeus His system was based on structural similarity. Back to Game Board
How many kingdoms were in this early system of classification? What were these kingdoms?
Linnaeus classified all organisms into two kingdoms: the plant kingdom and the animal kingdom. Back to Game Board
Name the seven levels of classification in the system proposed by Linnaeus.
Kingdom Phylum Class Order Family Genus Species Back to Game Board
In the system proposed by Linnaeus, what is the definition of a “species”?
Two organisms are placed in the same species when they can mate and produce fertile offspring. Back to Game Board
When classifying an organism today, what additional information is considered?
Cellular Organization Evolutionary Relationships Biochemical Similarities Genetic Similarities Embryological Similarities Back to Game Board
The system of naming that assigns a scientific name consisting of two parts.
Binomial Nomenclature Back to Game Board
The scientific name consists of the genus and the species names. Back to Game Board
Latin Back to Game Board
The scientific name must be written in italics or underlined. The genus is capitalized and the species is never capitalized. Back to Game Board
What taxonomic level has most recently been added to the 7 levels of classification?
Domains Back to Game Board
Domain Archaebacteria Domain Bacteria Domain Eukarya Back to Game Board
Kingdom Protista Kingdom Fungi Kingdom Plantae Kingdom Animalia Back to Game Board
Which kingdom contains organisms with the following characteristics? • prokaryotic • unicellular • cell walls do not contain peptidoglycans • very ancient and primitive
Kingdom Archaebacteria Back to Game Board
Which kingdom contains organisms with the following characteristics? • Eukaryotic • Cell walls composed of chitin • No chloroplasts • Heterotrophs
