Across
  1. 6. Region where the cell's microtubules are initiated; contains a pair of centrioles
  2. 7. Produces a usable form of energy (ATP) for the cell
  3. 8. Membrane enclosing the cell
  4. 10. Double membrane enclosing the nucleus
  5. 13. Many cells secrete proteins that are produced by ribosomes
  6. 15. Sticky layer made mostly of collagen that holds animal cells together
  7. 16. Projections that increase the cell's surface area
  8. 17. Organelle active in synthesis, modification, sorting, and secretion of cell products
  9. 18. Produces hydrogen peroxide as a by-product and then converts it to water
  10. 19. Material consisting of DNA and proteins
  11. 20. Cell control center
  12. 22. Motility structure present in some animal cells
  13. 24. Reinforces cell's shape, functions in cell movement
Down
  1. 1. Lipids manufactured here; breaks down drugs and toxin in liver
  2. 2. Changes in cell shape; muscle contraction; cytoplasmic streaming in plant cells
  3. 3. Anchorage of nucleus and certain other organelles
  4. 4. Sac of digestive enzymes (macromolecules are hydrolyzed)
  5. 5. The region of the cell between the plasma membrane and the nucleus
  6. 9. Maintenance of cell shape; cell motility; chromosome movements in cell division
  7. 11. Cytoplasmic channels through cell walls that connect the cytoplams of adjacent cells
  8. 12. May store water, needed chemicals and wastes in plant cells
  9. 14. Photosynthetic organelle; converts energy of sunlight to chemical energy stored in sugar molecules
  10. 21. Small structure that makes protein
  11. 23. Rigid covering of a plant cell; maintains cell's shape and protects cell from damage
