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