  1. 3. Fine, threadlike proteins found in the cell's cytoskeleton
  2. 6. A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement
  3. 10. Collapse of a walled cell's cytoplasm due to a lack of water
  4. 11. the rupturing of a cell due to excess internal pressure
  5. 12. Movement of molecules through the plasma membranes (typically opposite the dictates of osmosis or different) aided by a process that requires energy
  6. 13. Threadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments
  7. 14. A solution in which the concentration of solutes is less than that of the cell which resides in the solution
  8. 15. A vacuole that holds that matter which a cell engulfs
  9. 16. A lipid in which one of the fatty acid molecules has been replaced by a molecules that contains a phosphate group
  10. 17. Spiral strands of protein molecules that form a tubelike structure
  11. 18. A solution in which the concentration of solutes is essentially equal to that of the cell which resides in the solution
  12. 20. Organelles that contain pigments used in photosynthesis
  13. 21. Vacuoles that contain the waste products of digestion
  14. 22. Cluster of DNA, RNA, and proteins in the nucleus of a cell
Down
  1. 1. The organelles where proteins and lipids are stored and then modified to suit the needs of the cell
  2. 2. Movement of molecules through the plasma membrane according to the dictates of osmosis or diffusion
  3. 4. A large vacuole that rests at the center of most plants cells and is filled with solution that contains a high concentration of solutes
  4. 5. Energy necessary to get a chemical reaction going
  5. 7. Vesicle formed at the plasma membrane to allow the absorption of large molecules
  6. 8. A solution in which the concentration of solutes is greater than that of the cell which resides in the solution
  7. 9. A vesicle that holds secretion products so that they can be transported to the plasma membrane and released
  8. 15. The process by which a cell engulfs foreign substances or other cells
  9. 19. A highly-porous membrane that separates the nucleus from the cytoplasm
