Cell Parts/Processes

2. cell organelle filled with enzymes needed to break down certain materials in the cell
4. process by which a cell takes material into the cell by in folding of the cell membrane
8. filament long, thin fiber that functions in the movement and support of cell
9. group of similar cells that perform a particular function
10. process by which the number of chromosomes per cell cut in half through the separation of homologous chromosomes in a diploid cell
11. hollow tube of protein that maintains cell shape and that can be used as a "track" along which organelles are moved
15. diffusion of water through a semipermeable membrane
16. process that doesn't require oxygen
17. envelope double-layer membrane that surrounds the nucleus of a cell
18. respiration process that releases energy by breaking down food particles in the presence of oxygen

1. 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
3. process in which cells release energy in the absence of oxygen
5. process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
6. granular material visible within the nucleus
7. part of eukaryotic cell division in which the cell nucleus divides
12. small particle in cell on which proteins are assembled
13. reticulum internal membrane system in cells in which components of the cell membrane are assembled and some proteins modified
14. process that requires the presence of oxygen
19. bylayer double-layered sheet that forms the core of nearly all cell membranes
