Distinguish between the structures of prokaryotic and eukaryotic cells. 4. Explain how cell size is limited. 5. Describe the structure and functions of cell membranes. 6. Explain why compartmentalization is important in eukaryotic cells. 7. Compare the structures of plant and animal cells. Note the function of each  cell part. 8. Compare the structures and functions of chloroplasts and mitochondria. 9. Describe the evidence that suggests that mitochondria and chloroplasts  evolved by endosymbiosis. 10. Compare the structures and functions of microfilaments, intermediate  filaments, and microtubules. 11. Relate the structure of cilia and flagella to their functions. 12. Relate the structure of the extracellular matrix to its functions. 13. Compare the structures and functions of tight junctions, anchoring junctions  (desmosomes), and gap junctions. 14. Relate the structures of plant cell walls and plasmodesmata to their functions. 15. Describe the four functional categories of organelles in eukaryotic cells. Chapter  5     Cellular transport 1. Define the following terms: amphipathic molecules, aquaporins, diffusion 2. Explain how membrane fluidity is influenced by temperature and membrane  composition 3. Distinguish between the following pairs or sets of terms: peripheral and integral  membrane proteins; channel and carrier proteins; osmosis, facilitated diffusion, and  active transport; hypertonic, hypotonic, and isotonic solutions 4. Explain how transport proteins facilitate diffusion 5. Explain how an electrogenic pump creates voltage across a membrane, and name  two electrogenic pumps 6. Explain how large molecules are transported across a cell membrane 7. Be able to work tonicity problems (u­tube, dialysis bag, see text and MB for  practice materia Chapter 5.6  1. Describe the steps of a cell signaling 2. Describe the nature of a ligand­receptor interaction and state how such  interactions initiate a signal­transduction system 3. List two advantages of a multistep pathway in the transduction stage of cell  signaling 4. Explain how an original signal molecule can produce a cellular response when it  may not even enter the target cell 5. Define the term second messenger; briefly describe the role of these molecules in  signaling pathways 6. Explain why different types of cells may respond differently to the same signal  molecule 7. Describe the fine­tuning that goes on during the cellular response. Chapter 17 1. Identify the main structural components of viruses             Recognize how structural components are different than a cell 2. Distinguish between the lytic and lysogenic reproductive cycles             Compare to mitosis (after mitosis is covered in the semester) 3. Explain why viruses are obligate intracellular parasites and are not considered  living 4. Explain what characteristics of life (Ch. 1) viruses possess and which they lack.  Give examples of the characteristics in viruses and cells 5. Describe the reproductive cycle of an HIV retrovirus 6. Explain why a person infected with a virus might experience no symptoms for  exended periods of time with flare­ups every now and then. 7. Describe three processes that lead to the emergence of new diseases 8. Briefly explain how vaccines work 9. Describe viroids and prions
