    Prokaryotic
  7. fluid portion of the cell outside the nucleus
    Cytoplasm
  8. specialized structure that performs important cellular functions within a eukaryotic cell
    Organelle
  9. cell organelle that stores materials such as water, salts, proteins and carbohydrates
    Vacuole
  10. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell

  18. strong, supporting layer around the cell membrane in some cells
    Cell Wall
  19. flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
    Lipid Bilayer
  20. property of biological membranes that allows some substances to pass across it while others cannot; also called semi permeable membrane
