Biology Module 7a

1. A rigid structure on the outside of certain cells, usually plant and bacteria cells
4. Non-membrane bounded organelles responsible for protein synthesis
6. An organelle composed of an extensive network of folded membranes that performs several tasks within a cell
11. The removal of soluble waste materials
12. The transport of dissolved substance into cells
13. The removal of nonsoluble waste materials
14. The semipermeable between the cell contents and either the cell wall or the cell's surroundings
16. The release of biosyntesized substances
17. The organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and some lipids
19. the organelles in which nutrients are converted to energy
20. The breakdown of absorbed substances

1. The study of cells
2. Producing more cells
3. Maintaining the status quo
4. ER that is dotted with ribosomes
5. The breakdown of food molecules with a release of energy
7. Organelles that store starches or oils
8. Substances in which at least one atom has an imbalance of protons and electrons
9. the motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents
10. The thin film between the cell walls of adjacent plant cells
15. ER that has no ribosomes
18. A jellylike fluid inside the cell in which the organelles are suspended
