  1. 3. play a major role in cell division (mitosis)
  2. 5. do not have a nucleus and are more simple
  3. 7. concluded that all animals are made of cells
  4. 12. apparatus receives proteins from the rER and distributes them to other organelles or out of the cell (receiving, processing, packaging, and shipping)
  5. 13. membrane, selectively permeable boundary between the cell and the external environment
  6. 14. storage center of cell's DNA
  7. 16. location of protein synthesis
  8. 19. only in plant cells and where photosynthesis happens
  9. 20. the first person to observe living cells
  10. 22. surrounds the organelles
  11. 24. invented first microscope and observed "little boxes" which he called cells in cork
  12. 25. wall boundary around the plant cell outside of the cell membrane that provides structure and support
Down
  1. 1. an example is bacteria
  2. 2. degrades hydrogen peroxide
  3. 4. determined that cells come from only other cells
  4. 6. reticulum intercellular highway
  5. 8. ER prominent in cells that make large amounts of proteins to be exported from the cell or inserted into the cell membrane (covered with ribosomes)
  6. 9. concluded that all plant are made of cells
  7. 10. used for temporary storage of wastes, nutrients, and water
  8. 11. converts energy stored in food into usable energy for work
  9. 15. and flagella cell motility
  10. 17. have a nucleus and are more complex
  11. 18. ER involved in the synthesis of lipids and breakdown of toxic substances (not covered with ribosomes)
  12. 21. examples are animals, plants, fungi, and protists
  13. 23. breaks down food particles, invading objects, or worn out cell parts
