Across
  1. 1. structure in the nucleus which assembles ribosomes
  2. 3. The molecule that provides energy for the cell.
  3. 4. A protective layer that surrounds the cell membrane.
  4. 5. Vesicles that contain enzymes to break stuff down, animal cells only
  5. 6. Microtubules that help pull the DNA apart during cell division.
  6. 7. Molecules which do not dissolve in water; "water fearing."
  7. 8. ER that does not have any ribosomes attached to it.
  8. 12. A cell organelle which manufactures the cells energy molecule, ATP.
  9. 15. The types of lipid which make up the cell membrane.
  10. 17. A storage "sack" in the cytoplasm that holds food or wastes.
  11. 18. The study of cells.
  12. 21. lower the activation energy of reactions enough to allow them to occur safely in biological systems.
  13. 23. The state of being equal or even.
  14. 24. A mode of transport that does not require the cell to use any energy.
Down
  1. 2. Jelly-like substance the cell organelles float in
  2. 4. A type of plastid that performs photosynthesis.
  3. 9. Molecules which dissolve in water; "water loving."
  4. 10. Organelles that make proteins.
  5. 11. ER that has many ribosomes attached to it.
  6. 13. Units inside all cells which perform certain functions/tasks.
  7. 14. The movement of molecules from an area of higher concentration to an area of lower concentration.
  8. 16. A solution whose concentration of solute is lower than inside the cell.
  9. 19. The barrier around all cells which protects them from the outside world.
  10. 20. Organelles that either perform photosynthesis, or store material such as starch. They are found only in plants and algae.
  11. 22. requires the cell to use energy in order to move molecules across the membrane.
