  1. 1. A kingdom of unicellular, prokaryotic organisms that live in extreme environments and produce methane (examples: Methanogens, thermophiles,and halophiles)
  2. 6. A long, hair-like whip that is used for movement
  3. 8. A long molecule made of amino acids and sugars which makes up the cell wall of some organisms
  4. 11. The science of classifying living things
  5. 14. Organisms that must obtain their energy from an outside source; they cannot make their own food
  6. 16. Composed of many cells
  7. 17. A kingdom of multicellular, eukaryotic, heterotrophs, whose cells do not have cell walls (examples: humans, dogs, cats etc.)
  8. 18. A single cell

  1. 2. A polysaccharide found in the outer skeleton of insects, crabs, shrimps, and lobsters and in the cell walls of fungi
  2. 3. A classification grouping consisting of six groups
  3. 4. A kingdom of eukaryotic organisms that do not fit into the plant, animal or fungi kingdom. This is a very diverse group. (examples: Paramecium, Euglena)
  4. 5. A kingdom composed of heterotrophic, multicellular organisms that absorb dead or decaying matter for energy
  5. 7. An organism that can make its own energy
  6. 8. Multicellular organisms that contain chloroplasts and are autotrophs
  7. 9. Cells that lack a true nucleus; they do contain DNA or RNA
  8. 10. An organism that manufactures its own food through chemosynthesis (the oxidation of inorganic chemical compounds)
  9. 12. An organelle found in plants and some single cells that converts energy from the sun into glucose or sugar for the organism
  10. 13. A kingdom of unicellular, prokaryotic organisms that are very diverse(examples: Streptococcus; E. Coli)
  11. 15. Cells with a true nucleus, their DNA is surrounded by a nuclear membrane
