Chapter 8

4. fluid portion of the cell outside of the nucleus
6. internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled
8. organelle consisting of RNA and protein found throughout the cytoplasm; the site of protein synthesis
11. cell organelle that stores materials such as water, salts, proteins, and carbohydrates
13. flexible double layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
15. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
16. organism whose cells contain a nucleus
17. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
18. Ecosystem

1. unicellular organism that lacks a nucleus
2. a device that helps see small things
3. specialized structure that preform important cellular functions within a eukaryotic cell
5. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
7. organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell
9. strong, supporting layer around the cell membrane in some cells
10. structure that contains cell's DNA
12. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
14. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
17. Monomer of life
