  5. Prokaryotes lack a(n)______.
  6. Define eukaryote…be sure to also include three things that they contain….
  7. ______are prokaryotes (what organism?).
  8. ______-stores DNA, controls most of the cell’s processes, & contains information needed to make proteins.
  9. The ______is important to cells mainly because it contains coded instructions for making proteins.
  10. ______are organelles/structures found in the cytoplasm.
  11. ______-cell organelle that breaks down food into molecules the cell can use.
  12. ______-cell organelle/structure which makes protein using coded instructions from the nucleus.
  13. ______-organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
  14. ______&______are “energy organelles”…which help to provide a cell with energy.
  15. ______is an energy organelle you would expect to find in plant cells but not in animal cells.
  16. The ______helps a cell keep its shape…
  17. ______& ______are structures that help the cell to carry out cell movement…(cilia & flagella are NOT the answer for this particular question);
  18. The ______helps the cell maintain shape, helps the cell move & helps organelles within the cell move.
  19. The main function of the ______is to support & protect the cell.
  20. Unlike the cell membrane, the cell wall is usually made of tough ______.
  21. The ______serves as the cell’s boundary from its environment in most cells.
  22. The function of the ______is to regulate what materials enter & leave the cell.
  23. Diffusion is the movement of molecules from an area of______concentration to an area of ______concentration.
  24. What do the molecules do on each side of the membrane when the concentration of molecules on each side of the membrane is the same?
  25. ______transport is a means of particle transport that REQUIRES ENERGY.
  26. The DIFFUSION of WATER across a selectively permeable membrane is called ______.
  27. An animal cell that is surrounded by fresh water will______because the osmotic pressure causes water to move into the cell.
  28. ______refers to cells having different jobs in an organism.
  29. ______-a group of similar cells that perform a particular function. List an example.
  30. What is an organ system?
  31. List the levels of organization in a multicellular organism from simplest level to most complex beginning with cells.
  32. If a cell contains a nucleus, it must be a(n) ______.
  33. The assembly of ribosomes begins in a small dense structure called the ______.
  34. Ribosomes stud the surface of the ______.
  35. Cilia & flagella are made of protein filaments called ______.
  36. According to the cell theory, all cells come from existing ______.
  37. In a eukaryote, the material between the cell membrane & the nucleus is called the ______.
  38. During cell division, chromatin condenses to form ______, which are thread-like structures containing genetic material.
  39. Define diffusion.
  40. Be able to distinguish an animal cell from a plant cell by looking at an unlabeled diagram.
  41. From a diagram…be able to label (you have to be able to recognize/identify structures!) & tell the function of cell structures: nucleus, mitochondrion, ribosome, cell membrane, smooth endoplasmic reticulum, rough endoplasmic reticulum, nucleolus, golgi apparatus, cytoplasm;
