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 A lipid in which one of the fatty acid molecules has been replaced by a molecules that contains a phosphate group
