1. What are the major distinctions between eukaryotic cells and prokaryotic cells in terms of
   1. size?
   2. cell organization?
2. What are the three "domains of life"?
3. In what way is the eukaryote/prokaryote dichotomy misleading in terms of the evolutionary relationships among the three domains of life as we currently understand them?
4. What do we mean by "primary endosymbiosis" as accounting for the origins of mitochondria and chloroplasts?
5. What do we mean when we say that the chloroplasts of some algae appear to have evolved by "secondary endosymbiosis"?
6. Describe the major characteristics of connective tissue.
7. Indicate the functions of epithelial tissue.
8. Compare epithelila tissue and connective tissue in terms of the interactions among cells.
9. Describe the general structural features characteristic of the polarity of enterocytes.
10. Describe the sandwiching of different tissue layers to form the wall of the intestine.
11. In general, describe the structures and functions of the different types of alveolar epithelial cells.
12. Describe the secretory functions of hepatocytes.
13. Explain briefly the importance of regular connective tissue, especially loose connective tissue, in "connecting" cell types together into tissues. (You might try using the structure of the gut wall in developing your answer.)
14. Identify each of the following:

    	eukaryotic	apical surface
    	prokaryotic	basolateral surface
    	hydrogenosome	enterocyte
    	lysosome	goblet cell
    	hepatic	brush border
    	endothelium	longitudinal section
    	cytoskeleton	mucosa
    	extracellular matrix	lamina propria
    	fibroblast	submucosa
    	basal lamina	alveoli of lung
    	epithelial tissue	type I alverolar cell
    	squamous	type ii alveolar cell
    	columnar cells	bile caniliculus
    	lumen
