AP Biology Chapter 7 Assignment After reading this chapter and attending lecture, you should be able to: 1. Describe techniques used to study cell structure and function. 2. Distinguish between magnification and resolving power. 3. Describe the principles, advantages and limitations of the light microscope, transmission electron microscope and the scanning electron microscope. 4. Describe the major steps of cell fractionation and explain why it is a useful technique. 5. Distinguish between prokaryotic and eukaryotic cells. 6. Explain why there are both upper and lower limits to cell size. 7. Explain why compartmentalization is important in eukaryotic cells. 8. Describe the structure and function of the nucleus, and briefly explain how the nucleus controls protein synthesis in the cytoplasm. 9. Describe the structure and function of a eukaryotic ribosome. 10. List the components of the endomembrane system, describe their structures and functions and summarize the relationships among them. 11. Explain how impaired lysosomal function causes the symptoms of storage diseases. 12. Describe the types of vacuoles and explain how their functions differ. 13. Explain the role of peroxisomes in eukaryotic cells. 14. Describe the structure of a mitochondrion and explain the importance of compartmentalization in mitochondrial function. 15. Distinguish among amyloplast, chromoplast and chloroplast. 16. Identify the three functional compartments of a chloroplast, and explain the importance of compartmentalization in chloroplast function. 17. Describe probable functions of the cytoskeleton. 18. Describe the structure and functions of microtubules, microfilaments, and intermediate filaments. 19. Explain how the ultrastructure of cilia and flagella relates to their function. 20. Describe the structure and list some functions of the extracellular matrix in animal cells. 21. Describe the structure of intercellular junctions found in plant and animal cells, and relate their structure to function. Define the following terms: Magnification resolving power light microscope SEM Golgi apparatus cis face cell wall primary cell wall secondary cell wall extracellular matrix plastid amyloplast gap junctions tubulin thylakoid thylakoid space cell fractionation cytoplasm cytosol nucleus dynein actin chromoplast chloroplast cytoplasmic trans face lysosomes phagocytosis macrophages food vacuole vesicles centrosome myosin basal body TEM grana stroma cytoskeleton microtubules collagen microfilaments nuclear envelope intermediate filaments proteoglycan motor molecule fibronectin centriole integrin plasmodesmata mitochondria ribosome intermembrane space endomembrane system mitochondrial matrix endoplasmic reticulum (ER) contractile vacuole central vacuole chromosome nucleolus flagella smooth ER rough ER cilia chromatin tonoplast peroxisome desmosomes tight junctions
