List the 6 kingdoms used in the classification system: ________________________________ ________________________________ ________________________________ ________________________________ ________________________________ ________________________________ PART II: Match the following words to the correct description. _____ 1.

Vertebrate _____ 20. Species _____ 21. Phylogenic tree A. organisms that lack nuclei & membrane bound organelles; bacteria; were once part of the Kingdom Monera (but now make up the kingdoms of Archaebacteria & Eubacteria B. Animal with a backbone C. What biologists would use to create a cladogram D. The most general group that an organism can belong to is a E. organisms that have nuclei & membrane bound organelles F. Kingdom that contains organisms that have cell walls made of chitin and do not have chloroplasts G. Animal without a backbone H. Two organisms within the same species can be organized into several related I. rigid structure found outside of the cell membrane for support and shape J. structure found surrounding the cytoplasm of all cells; separates the contents of the cell from the environment; helps maintain homeostasis; is semipermeable K. composed of only one cell L. composed of many cells that function together to maintain the homeostasis of the organisms M. organisms that make their own food; do not eat N. organisms that make their own food using chloroplasts which capture light energy and convert it to chemical energy using CO2 & H2O; autotrophic O. organisms that eat other organisms; can not make their own food in their cells, tissues, or organs P. A branched diagram showing relationships of organisms and divergent evolution is called Q. Another name for a heterotroph R. Kingdom containing pathogens (disease causing bacteria) S. Kingdom containing organism without cell walls & chloroplasts T. Kingdom with organisms who are autotrophic but also have membrane-bound organelles U. Contains all eukaryotes found in the Kingdoms of Protista, Fungi, Animalia & Plantae PART III: Classifying Organisms Each of the following organisms is newly described. Based on the description, identify the domain and kingdom to which each belongs. 1. Organism 1 – composed of over 1 trillion cells, all of which contain a nucleus; feeds on worms & other invertebrates; reproduces sexually Domain ________________________ Kingdom _______________________ 2. Organism 2 – unicellular, heterotrophic, reproduces sexually, cell walls contain chitin Domain ________________________ Kingdom _______________________ 3. Organism 3 – only multicellular, autotrophic, aquatic, reproduces sexually, cells contain organelles that convert light energy to chemical energy with oxygen gas as a waste product Domain ________________________ Kingdom _____________ or _____________ 4. Organism 4 – one-celled organism, all cells lack membrane bound organelles, reproduce asexually, peptidoglycan found in cell walls Domain ________________________ Kingdom _______________________ 5. While exploring the jungles of Yucatan, you find a multicellular organism that is autotrophic and contains cellulose in its cell walls. It lives on land. Domain ________________________ Kingdom _______________________ 6. Still exploring the jungles of Yucatan, you notice a multicellular organism growing out of a dead tree and absorbing its nutrients as it decomposes the tree and is also fixing nitrogen. Its cells have cell walls with chitin. Domain ________________________ Kingdom _______________________ 7. You decide to go scuba diving off the coast of Yucatan and you find a microscopic organism that lives in the volcanic vents at the bottom of the ocean. Domain ________________________ Kingdom _______________________ 8. You find an organism that is unicellular and lives in the water. It contains membrane bound organelles. Domain ________________________ Kingdom _______________________ 9. When you get out of the water, you find a microscopic organism that lives on your skin. Its cells have no nuclei. Domain ________________________ Kingdom _______________________ PART IV: Use the phylogenetic tree to the following questions. 1. What species is most closely to the bird? right to answer the genetically related 2. What species is the least closely genetically related to the bird? Use the dichotomous key below to identify the following birds: 3. What is the name of Bird W? _______________________________________ 4. What is the name of Bird X? ________________________________________ 5. What is an advantage to having a universal naming system? 6. What is the genus of this organism: Dracaena marginata 7. What is an advantage to having a universal naming system?
