  1. 3. release chemical energy in food using cell respiration.
  2. 5. the net movement of water out of or into a cell that exerts a force.
  3. 7. helps the cell maintain its shape and is also involved in movement.
  4. 8. a substance is unable to cross a membrane.
  5. 9. capture the energy from sunlight and convert it into food in a process called photosynthesis.
  6. 12. is a strong supporting layer around the membrane and is found in many cells.
  7. 14. the movement of materials against a concentration difference using energy.
  8. 15. an internal membrane system that makes protein and lipids.
  9. 20. extensions of cytoplasm surround a particle and package it within a food vacuole.
  10. 21. produce a 3D image of an object’s surface.
  11. 23. channel proteins that allow water to pass rapidly through them, since they are hydrophilic and have a tough time passing through the hydrophobic cell membrane.

  13. 26. move materials in or out.
  14. 27. help to organize cell division in animals only.
  15. 34. modifies, sorts, and packages proteins and other materials from the ER for storage in the cell or release outside the cell.
  16. 35. have no nuclei and are generally smaller and simpler than eukaryotic cells.
  17. 37. enable cells to swim rapidly through liquids and are arranged in a “9 + 2” pattern.
  18. 38. was based on: All living things are made up of cells, cells are the basic units of structure and function in living things and new cells are produced from existing cells.
  19. 39. cells take up liquid from the surrounding environment by forming vesicles.
  20. 43. avoid water and form the interior of a cell membrane.
  21. 45. two layers of phospholipids and proteins that form a strong, flexible barrier between the cell and its surroundings.
  22. 48. large membrane-enclosed structure that contains the cell’s DNA, coded instructions for making proteins.
  23. 49. make plant cells more rigid for support.
  24. 50. is a molecule that carries biological information.
  25. 51. found bacteria and microbes in water.
  26. 52. lacks ribosomes and makes lipids and detoxifies drugs.
  27. 53. large, saclike, membrane-enclosed structures that store materials such as water, salts, proteins, and carbohydrates.
  28. 54. allow cells to identify one another.
  29. 55. break down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell.
