The Cell
Across
- 4. Also known as deoxyribonucleic acid; contains the genetic code for all cells
- 7. The control center of the cell
- 8. A jelly-like substance that suspends the organelles
- 9. Clusters of DNA, RNA, and proteins
- 10. The green pigment found in plant cells that gives plants their green coloring
- 11. A network of fibers that hold the cells together
- 12. The aqueous component of cytoplasm (70 percent water)
- 13. Makes proteins
- 14. Moves the cell back and forth through short cell projections
- 15. Store food in plant cells
- 16. Stores proteins and lipids
- 17. Spiral strands of protein forming a tubelike structure
- 20. Organize microtubules
- 21. Propels the cell through thin projections from cell surface
- 22. Large protein molecules that exert strict control over which chemical reactions occur and when
- 23. Converts glucose/energy into ATP; has its own DNA
Down
- 1. Also known as the ER; rough ER has ribosomes, smooth ER does not have ribosomes
- 2. Sacs that transport materials in and out of the cell
- 3. A membrane-bound sac and some contain digestion waste products
- 5. The inner folds of mitochondria
- 6. Forms ribosomes in the cell
- 14. Only in plant cells; a rigid structure outside of the cell
- 18. Performs photosynthesis in plant cells
- 19. Breaks down molecules through hydrolysis
- 20. The semi-permeable membrane that allows H2O and O2 into the cell, but not toxins.
