Across
- 1. reticulum internal membrane system in cells in which components of the cell membrane are assembled and some proteins modified
- 7. group of similar cells that perform a particular function
- 8. process in which cells release energy in the absence of oxygen
- 10. hollow tube of protein that maintains cell shape and that can be used as a "track" along which organelles are moved
- 13. respiration process that releases energy by breaking down food particles in the presence of oxygen
- 15. process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
- 16. process by which the number of chromosomes per cell cut in half through the separation of homologous chromosomes in a diploid cell
- 18. small particle in cell on which proteins are assembled
Down
- 2. envelope double-layer membrane that surrounds the nucleus of a cell
- 3. process by which plants and some other organisms use light energy to power chemical reactions to convert carbon dioxide and water into oxygen and high-energy carbohydrates such as sugars and starches
- 4. process that requires the presence of oxygen
- 5. part of eukaryotic cell division in which the cell nucleus divides
- 6. diffusion of water through a semipermeable membrane
- 9. process that doesn't require oxygen
- 11. granular material visible within the nucleus
- 12. process by which a cell takes material into the cell by in folding of the cell membrane
- 14. bylayer double-layered sheet that forms the core of nearly all cell membranes
- 17. cell organelle filled with enzymes needed to break down certain materials in the cell
- 19. filament long, thin fiber that functions in the movement and support of cell
