The Cell

4. An organelle composed of an extensive network of folded membranes.
5. Allows charged ions to pass through.
6. The organelle responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and lipids.
9. The study of energy transformation within systems.
10. Concentration of solutes is equal to that of a cell.
11. Holds animal cells together are helps them to maintain shape.
17. The processes to get substances out of the cell.
18. Large protein molecules in all cells which exert strict control over which chemical reactions occur and when.
19. A jellylike fluid inside the cell in which the organelles are suspended.
21. The organelles in which nutrients are converted to energy (ATP).
24. A vesicle formed at the plasma membrane.
25. Maintaining a stable internal environment.

1. Organelles that store starches or oils.
2. Non-membmembraned organelles responsible for protein synthesis.
3. The control center of the cell.
7. A vesicle that holds secretion products.
8. The semi-permeable membrane between the cell's contents.
12. A membrane-bound "sac".
13. Cells are the basic units of structure and function for all life.
14. A network of fibers that holds the cell together, keeps the cell's shape, and aids in movement.
15. A rigid structure on the outside of plant cells.
16. A type of transport that does not require ATP.
20. The study of cells.
22. The organelles where proteins and lipids are stored and modified to suit the cell's needs.
23. The process of making molecules using absorbed molecules.
