3. Apparatus In eukaryotic cells, proteins produced in the rouge ER move next into an organelle.
4. The diffusion of water through a selectively permeable membrane.
5. The dilate sugar solution "below strength".
7. the more concentrated sugar solution "above strength".
13. An organelle in the cytoplasm of cells that functions in energy production.
15. Wall The definite boundary or wall that is part of the outer structure of certain cells.
16. A cell organelle containing enzymes that digest particles and that disintegrate the cell after it's death.
17. Permeable Meaning that some substances can pass across then others cannot.
21. The process by which particles move from an area of high concentration to an area of lower concentration.
24. A control part about which other parts are grouped or gathered.
25. Located near the nucleus and help organize cell division.

1. Cells that do not enclose DNA in nuclei.
2. Pressure Driven by differences in solute concentration the net movement of water out of or into a cell produces.
6. The tendency of the body to seek and maintain a condition of balance or equilibrium within its internal environment, even when faced with external changes.
8. Small particles of RNA and protein found throughout the cytoplasm in all cells.
9. Cells that enclose their DNA in nuclei.
10. Bilayer Cell biology
11. A specialized part of a cell having some specific function.
12. diffusion In which molecules that cannot directly diffuse across the membrane pass through special protein channels.
14. Eukaryotic cells are given their shape and internal organization.
18. Reticulum Eukaryotic cells contain an internal membrane system.
19. A plastid containing chlorophyll.
20. A membrane-bound cavity within a cell often containing a watery liquid or secretion.
22. "same strength" strength refers to the amount of solute not water.
23. Any of various small compartments or bounded areas forming put of a whole.
