  1. 3. A taxonomic group that ranks below kingdom and above clas, grouping organisms based on major body plans or structures.
  2. 7. largest grouping in the classification of organisms, above kingdom
  3. 10. Classification system)" A way scientists organize living things into groups based on shared characteristics and relationships.
  4. 12. the only kingdom in the domain Bacteria, consists of diverse unicellular prokaryotes that have cell walls
  5. 13. group a category used to organize organisms in a classification system, such as kingdom, phylum, class, order, family, genus, or species.
  6. 14. kingdom of multicellular eukaryotic heterotrophs whose cells do not have cell walls
  7. 16. A taxonomic grou that ranks below class and above family, grouping related families together
  8. 17. Wall A thick outer structure on the outside of a cell.
  9. 19. Nomenclature a naming system created by Carolus Linnaeus in which every organism is given a two part name
  10. 20. kingdom composed of eukaryotes that are not classified as plants, animals, or fungi
  11. 22. second largest grouping in organism classification, as in the animal kingdom
  12. 23. a group in tghe taxonomic hierarchy that ranks below phylum and above order. It groups organisms that share similar characteristics.

  2. 2. (Eukaryotic) have a nucleus in each cell that contains genetic material
  3. 4. related to the system scientists use to classify and organize living things
  4. 5. (Prokaryotic) organisms whose cells lack a nucleus and whose genetic material floats freely in the cell
  5. 6. A taxonomic group that ranks below order and above genus, grouping closely related organisms.
  6. 8. Classification System and
  7. 9. kingdom composed of heterotrophs; many obtain energy and nutrients from dead organic matter
  8. 11. kingdom of microscopic unicellular prokaryotes that have cell walls and reproduce asexually
  9. 15. Organisms that cannot make their own food. They must consume (eat) other organisms
  10. 18. Linnaeus the scientist that developed the classification system we use today
  11. 21. kingdom of multicellular photosynthetic autotrophs that have cell walls
