Name______________________________ Unit 2 Classification (chapter 18) Test Review Know how to read/interpret a cladogram. Read Miller and Urey’s experiment Read Germ theory and Koch’s postulates Know similarities and differences between viruses and living cells. Be able to give examples of organisms in each of the 6 kingdoms. Must study from notes, handouts, assignments Use Notes (6 kingdom chart) and textbook to complete this test review. 1. The science of grouping organisms on the basis of their similarities is called Taxonomy 2. The practice of using two word names for scientific names is known as Binomial Nomenclature. 3. The scientific name consists of what two parts? genus and species 4. Write the name CANIS LUPUS correctly. Canis lupus 5. A dichotomous key gives a list of choices that lead to the name of an organism being identified. 6. Derived characteristics are used to generate a cladogram, a diagram that shows relationships among groups of organisms in terms of evolution. 7. Traditional classification considered only physical characteristics and structural similarities of organisms for classifying them. 8. The modern taxonomists study the following characteristics of organisms to determine relationships among organisms. Structural similarities, DNA, Biochemical similarities, Embryological development, Reproductive potential, Evolutionary history. 9. List the 7 levels of taxonomy, from largest (most inclusive) to smallest. a. Kingdom e.Family b. Phylum f. Genus c. Class g. Species d. Order 10. Complete the chart below. Domain Kingdom Archaea Archaebacteia Bacteria Eubacteria Fungi, Protista, Plantae and Animalia. Eukarya 11. Organisms that do not contain a nucleus are called prokaryotic Organisms that DO contain a nucleus are called Eukaryotic 12. An organism that can produce its own food is known as a(n) Autotroph An organism that must obtain food is known as a(n) Heterotroph 13. In what Kingdom do we find most eukaryotes that are either heterotrophic or autotrophic? Protista 14. A new organism was discovered. It has no nucleus and lives in a high-temperature pool. To what kingdom does it belong? Archaebacteria 15. Another new organism was found nearby. It is a heterotroph, has a cell wall, and gets nutrients from decomposing matter. To what kingdom does it belong? Fungi, or Eubacteria 16. Another organisms was found that is an autotroph and has no nucleus. To what kingdom does it belong? Eubacteria (it is cyanobacteria – which can photosynthesize) 17. Scientists have found that humans and yeasts have similar genes for the assembly of certain proteins. Similar genes are evidence of common ancestry. 18. Which of the following are sister taxa? D&E B&C A&D C&D 19. Cladograms In the cladogram above which species are sister taxa? a) Lizard and Chicken b) Chipmunk and Cougar Which species have an amnion (a membrane around an embryo)? Lizard, Chicken, Chipmunk and Cougar According to the above cladogram, did the chicken evolve from the lizard? No 20. The kingdom Animalia contains many different organisms. Which organism(s) does (do) not have tissues? Sponge 21. According to the cladogram above, which is (are) correct? i. ii. iii. salamanders and lizards are sister taxa lizard evolved from salamanders lizards, hamsters, and chimpanzees have claws A. i B. ii C. iii D. i and ii E. i and iii F. ii and iii G. i, ii, and iii 22. If two organisms are similar and can produce fertile offspring, they are probably members of the same species. 23. What phylum are the classes Reptila and Mammalia in? Chordata 24. Organisms, such as humans, that get their body heat from metabolism are called endothermic. Reptiles, amphibians, etc that have to use the outside environment to maintain their temp are ectothermic. 25. Earth’s early atmosphere contained little or no oxygen gas . Cyanobacteria, single-celled prokaryotic produced oxygen, as an end product of photosynthesis. 26. Using the cladogram below, Determine which two organisms are most closely related. Reptiles & Birds 27. According to this cladogram, what is a characteristic that birds and living reptiles have that mammals, amphibians and fish do not? 2 holes in skull behind eye 28. What is the one characteristic that all of these organisms share? backbone KINGDOM PHYLUM CLASS ORDER FAMILY GENUS SPECIES HUMAN Animalia Chordate Mammal Primates Hominidae Homo sapiens CHIMPANZEE Animalia Chordate Mammal Primates Pongidae Pan troglodytes HOUSE CAT Animalia Chordate Mammal Carnivora Felidae Felis domestica LION Animalia Chordate Mammal Carnivora Felidae Felis leo HOUSEFLY Animalia Arthropoda Insect Diptera Muscidae Musca domestica 29. Look at the table above, Which organism is most closely related to the chimp? human The lion is most closely related to the House cat 30. The graph shown here looks at how mutations occur at a fairly constant rate. This is called a Molecular clock 31. Viruses are not considered to be alive according to the current definition of life? What characteristics of life do they not show? Cannot reproduce outside host A. worms B. plankton C. mushrooms D. E. coli E. thermophiles F. prokaryote G. eukaryote H. heterotroph I. autotroph J. unicellular K. multicellular L. has cell wall M. no cell wall N. algae O. dandelion P. squid Q. spinach 32. Matching E,F, H, I, J,L Archaebacteria D,F, H, I , J, L Eubacteria B, G,I,K,L,N, Protist C, G, H, J, K, L, Fungi G, I, K, L, O, Q Plantae A, G, H, K, M, P Animalia 33. What procedure did Koch use to identify the cause of a disease? Infectious agent must be present in every case of the disease Infectious agent must be extracted from an diseased individual, isolated from all other microorganisms, and grown independently in laboratory culture The cultured infectious agent, must create the same disease when introduced into a healthy test individual of the same species The supposed infectious agent must be extracted from the test individual and shown to be the same microorganism 34. Using the dichotomous key below, identify the organism Virginia bluebell (Hint: All the plants have blue or purple flowers with five petals that are fused together). 35. More practice: What are the 6 kingdoms of life? 1. Eubacteria 2. Archaebacteria 3. Protista 4. Fungi 5. Plantae 6. Animalia Find out kingdom in which the following organisms belong? (Use flipchart available on the website) 1. Mushrooms and yeast - Fungi 2. Most photosynthetic autotrophs - Plantae 3. Homo sapien - Animalia 4. Organism that have wall of chitin - Fungi 5. Invertebrates and vertebrates - Animalia 6. Organisms that live in extreme conditions, at deep ocean vents and hot springs - Archaebacteria 7. Protozoans and brown, yellow, green and red algae - Protista 8. Ferns, shrubs, grasses, trees - Plantae 9. A sea sponge - Animalia 10. Bacteria and blue-green algae - Eubacteria 11. Mammalia & Reptilia - Animalia 12. Mosses - Plantae 13. Mold and mildew - Fungi 14. Paramecium, Amoeba - Protist 15. Single-celled and multi-celled organisms- Fungi & Protista
