  1. 4. One of several modes of transport that require the cell to expend energy in order to move molecules across the membrane
  2. 6. ER that does not have any ribosomes attached to it
  3. 8. Cells that contain a nucleus and membrane-bound organelles
  4. 13. Vesicles that contain enzymes to break stuff down,only in animal cells
  5. 14. The study of cells
  6. 15. The sticky layer that holds plant cells together
  7. 18. A storage "sack" in the cytoplasm that holds food or wastes
  8. 19. The theory that cells are the basic units of structure and function for all life
  9. 20. Structure in the nucleus which assembles ribosomes
  10. 22. Microtubules that help pull the DNA apart during cell division
  11. 24. Stores the DNA
  12. 25. The barrier around all cells which protects them from the outside world
Down
  1. 1. Pinched off part of the cell membrane that stores and transports substances
  2. 2. A type of plastid that performs photosynthesis
  3. 3. Cells that don't have a nucleus nor any membrane-bound organelles
  4. 5. Jelly-like substance the cell organelles float in, fills the inside of a cell
  5. 7. Units inside all cells that perform certain functions/tasks
  6. 9. Organelles that make proteins
  7. 10. A complex network of proteins that strengthen the cell and keep it from rupturing
  8. 11. The types of lipid that make up the cell membrane
  9. 12. A series of tubes and membranes that store, modify, and package the products received from the ER
  10. 16. A cell organelle that manufactures the cells' energy molecule, ATP
  11. 17. The molecule that provides energy for the cell
  12. 21. A protective layer that surrounds the cell membrane in plant cells
  13. 23. ER that has many ribosomes attached to it
