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