Across
- 5. Located near the nucleus and helps to organize cell division; not found in plant cells
- 8. Large, saclike, membrane-enclosed structure used for storage
- 10. Type of transport where materials move against a concentration difference; requires energy
- 12. The fluid portion of the cell outside the nucleus
- 14. Small organelles filled with enzymes that function as the cell's cleanup crew
- 15. The process of taking material into the cell by means of infoldings, or pockets in the cell membrane
- 18. Internal membrane system that helps with protein synthesis and the creation of membrane lipids
- 19. the process by which particles move from an area of high concentration to an area of low concentration
- 22. Cell that encloses its DNA in a nucleus and has membrane-bound organelles
- 23. Organelle that captures the energy from sunlight and converts it into food
- 25. Large membrane-enclosed structure that contains the cell’s genetic material
Down
- 1. Network of protein filaments; made of microtubules and microfilaments
- 2. Cell that has free-floating DNA and few organelles
- 3. Small particles of RNA and protein found throughout the cytoplasm in all cells
- 4. The diffusion of water through a selectively permeable membrane
- 6. Relatively constant internal physical and chemical conditions
- 7. Type of transport where movement of materials across the membrane doesn't require energy
- 9. Membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell
- 11. Type of diffusion in which molecules use protein channels to cross a membrane they wouldn't ordinarily be able to cross
- 13. Thin barrier surrounding a cell
- 16. Stack of flattened membranes that prepares substances for storage or removal from the cell
- 17. The powerhouse of the cell
- 20. Group of tissues working together
- 21. Strong supporting layer around the cell membrane
- 24. Group of cells that performs a similar function
