1 Organizing Life s Diversity Section 17.1 Classification Scan Section 1 of your book. Write three questions that come to mind from reading the headings and the illustration captions Review species Use your book to define the following term. New binominal nomenclature class division family genus kingdom order phylum specific epithet classification Classify each term at the left as being part of Linnaeus two-word naming system or a taxonomic group. The number of terms in each column is given to you. Linnaeus System (3) Taxonomic Group (6) Use your book to define each term. taxonomy 162 Classification
2 Section 17.1 Classification (continued) How Classification Began Identify the parts of Linnaeus two-word naming system by completing the graphic organizer below. Binomial Nomenclature: first word identifies a which is a second word is called the which often describes Name the genus and specific epithet for the species name of modern humans. genus specific epithet Modern Classification Explain why scientists now think that dinosaurs are more closely related to birds than to reptiles. Describe three uses of taxonomy Organizing Life s Diversity 163
3 Section 17.1 Classification (continued) How Living Things are Classified Organize the following taxa from most specific to least specific: family, genus, order, species. The first one has been done for you. species Examine the figure of the taxonomic groups in your book. Then identify the kingdom, phylum, and class for humans. Kingdom: Phylum: Class: ANALOGY Create your own organizer that shows where you live in a similar way that a classification system works. For example, you may want to indicate the continent you live on, your country, state, county, and town in your home classification. 164 Classification
4 Organizing Life s Diversity Section 17.2 The Six Kingdoms Compare and contrast What physical characteristics do you share with your parents? What physical characteristics make you different from them? Review archaebacteria Use your book to define the following term. New cladistics cladogram eubacteria fungus phylogeny Use your book to define each term. protist Organizing Life s Diversity 165
5 Section 17.2 The Six Kingdoms How are evolutionary relationships determined? Identify the five characteristics that are the basis for evolutionary relationships. Evolutionary Relationships Explain how scientists came to the conclusion that giant pandas and red pandas are not closely related to each other. Phylogenic Classification: Models Compare two models that are used to show the phylogeny of a species by completing the table below. Write two facts about each model. Cladogram Fan-Shaped Diagram 166 The Six Kingdoms
6 Section 17.2 The Six Kingdoms The Six Kingdoms of Organisms Identify each kingdom with its description by placing the letters on the appropriate lines. a. animals c. eubacteria e. plants b. archaebacteria d. fungi f. protists have strong cell walls, cause diseases are stationary unicellular or multicellular heterotrophs live in extreme environments are multicellular autotrophs, cells have walls have simple organ systems all are multicellular heterotrophs Summarize the main characteristics of organisms by writing at least one fact in each box. Kingdom Cell Structure Energy Sources Other Characteristics Eubacteria Archaebacteria Protists Fungi Plants Animals COMPARE Provide one example of how chemosynthetic organisms are different from photosynthetic organisms.
