Chapter 7 Study Guide 1. Look over diagrams of plant and animal cells on page 174 and be able to identify each organelle. 2. Know the function of each organelle. 3. How do eukaryotes differ from prokaryotes? 4. Know organelles that are found in plant cells and not animal cells. 5. Read "Cell Membrane" on page 184. 6. What is the difference between active and passive transport? 7. Give examples of active and passive transport. 8. Figure 7-18. 9. Define hypertonic, hypotonic, and isotonic. 10. What is osmosis? 11. Give an example of a solute. 12. State the three parts of the cell theory. 13. Define endocytosis and exocytosis. 14. Give two examples of endocytosis. 15. Where is DNA located in the cell of a eukaryote? Is it different in a prokaryote? 16. What will happen when a cell is placed in a hypertonic environment? 17. What will happen when a cell is placed in a hypotonic environment? 18. What will happen when a cell is placed in an isotonic environment? 19. What is a concentration gradient? 20. What is a chromosome? 21. What is a selectively permeable membrane? 22. What is pumped into and out of a cell via the sodium/potassium pump? What is the role of ATP in this type of pump? 23. What is diffusion? Facilitated diffusion? 24. What types of molecules can pass directly through the lipid bilayer of the cell membrane?
