  1. 1. cell that contains a nucleus and other membrane-bound organelles
  2. 2. a polysaccharide polymer in the bacterial cell wall that is composed of sugars and amino acids
  3. 3. structure found in all cells that is the site of protein synthesis
  4. 4. an antibiotic made from fungus that works against a variety of bacterial species
  5. 5. structure within the cytoplasm of a cell that is enclosed within a membrane and performs a specific job
  6. 9. organelle in eukaryotic cells that uses energy stored in glucose to make ATP, which cells can use for energy
  7. 13. a rod-shaped bacterium
  8. 15. small, circular piece of DNA in a prokaryotic cell
  9. 16. material inside the cell membrane, including the watery cytosol and other cell structures except the nucleus if one is present
  10. 17. species that is harmed in a parasitic relationship

  12. 21. double-stranded nucleic acid that stores genetic information; also known as deoxyribonucleic acid
  13. 24. rigid layer that surrounds the cell membrane in plants, fungi, and bacteria that helps support and protect the cell
  14. 25. the ability to do work
  15. 26. thin coat of phospholipids that surrounds a cell and controls what enters and leaves the cell
  16. 27. long, whip-like extensions on the surface of a cell that helps the cell move
  17. 29. protective layer outside the cell wall of many prokaryotes; protects the cell from chemicals and from drying out.
  18. 32. a region within the cytoplasm of a prokaryote where DNA is contained in a large, circular strand
