1 NAME: DATE: PER: CLASSIFICATION OF LIFE Powerpoint Notes 1. Species of Organisms a) There are known species of organisms b) This is only of all organisms that ever lived. c) are still being found and identified. 2. What is Classification? a) Classification is the arrangement of organisms into orderly based on their. b) Classification is also known as. c) are scientists that identify and name organisms. 3. Benefits of Classifying a) and names organisms. b) Prevents such as starfish and jellyfish that aren't really fish. c) Uses ( or some ) for all names. 4. Confusion in Using Different Languages for Names this smelly creature is called a) b) c) d) e) 5. Latin Names are Understood by all Taxonomists. The scientific name of the creature is.

2 6. Early Taxonomists a) 2,000 years ago, was the first taxonomist. b) He divided organisms into and c) He them by their, land, sea or air dwellers. 7. Early Taxonomists a), a was the first to use Latin for naming. b) His were descriptions telling everything about the plant. 8. Carrolus Linnaeus a) 18 th century b) Classified organisms by their c) Developed a still being used today. 9. Carrolus Linnaeus (second slide) a) Called the b) Developed the modern system of naming known as c) - name (Genus & species) 10. Standardized Naming a) used b), c) Latin or Greek d) in print e), but NOT species. f) when writing g) The scientific name for the American Robin is

3 11. Binomial Nomenclature. The scientific name for each of these bears is: a) Giant Panda = b) Polar Bear = c) Grizzly Bear = 12. Rules for Naming Organisms a) The contains the rules for naming organisms b) All names must be approved by (International Zoological Congress) c) This names. 13. Classification Groups a) ( -plural) is a category into which related organisms are placed b) There is a of groups (taxa) from broadest to most specific. c),,,,,,, 14. Hierarchy Taxonomic Groups a) In plants, the term is used instead of Phylum. 15. A common mnemonic device to help remember the order is a) ing hillip ame ver or ooseberry oup! b) Now, make your own mnemonic device! Kingdom = Phylum (Division) = Class = Order = Family =

4 Genus = Species = 16. Classification of Humans Classification Category Domain Eukarya Kingdom Animalia Phylum Chordata Class Mammalia Order Primates Family Hominidae Genus Homo Species sapiens Characteristics 17. Domains a) most inclusive taxon b) domains c) and are unicellular prokaryotes (no nucleus or membrane-bound organelles) d) are more complex and have a nucleus and membranebound organelles. 18. live in and may represent the first cells to have evolved. They are often found in etc. 19., some of which cause human diseases, are present in almost on Earth. They live in. Many bacteria are important and

5 20. Domain Eukarya is Divided into Kingdoms a) (protozoans, algae, etc.) b) (mushrooms, yeasts, etc.) c) (multicellular plants) d) (multicellular animals) 21. Protista a) b) Some are multicellular c) Some are (make their own food) while others are (cannot make their own food) 22. Fungi a) except yeast b) (digest food outside their body and then absorb it) c) cell walls are made of 23. Plantae a) b) c) Absorb to make glucose Photosynthesis d) Cell walls are made of 24. Animalia a) b) (consume food and digest it inside their bodies) c) Feed on 25. Tree diagram showing domains and kingdoms.

6 26. Domain Eukarya is subdivided into four kingdoms.

7 27. Taxons a) Most contain a number of similar species, with the exception of, that contains ONLY modern humans. b) Classification is based on 28. Pie graph showing the relative numbers of species in each domain and kingdom. 29. Basis for Modern Taxonomy a) (same structure, different function) b) Similar development c) Similarity in, or sequence of proteins. 30. show similarities in mammals. 31. Similarities in Vertebrate Embryos 32. Cladogram a) Diagram showing how organisms are related based on. such as feathers, hair or scales. 33. Primate Cladogram shows human similarities and differences to other primates. 34. Dichotomous Keying a) Used to identify organims b) Characteristics given in c) and either go to another set of characteristics identify the organism. 35. Example of Dichotomous Key
