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