Why might this have limited their understanding of cells?ANSWER:??Prokaryotes are the most common of cells. By not understanding them, they could have missed something very important. Fortunately, the cell theory was stated broadly enough that this was not a problem and subsequent research shows prokaryotes are not an exception to this theory.DIFFICULTY:??Bloom's: UnderstandREFERENCES:??4.2 What Is A Cell?LEARNING?OBJECTIVES:??UDOL.STES.16.4.2 - Examine the principles of cell theory.104.?Prokaryote means "before the nucleus", but what general feature could prokaryotes also be said to lack?ANSWER:??Prokaryotes generally lack any organelles, and are poorly compartmentalized.DIFFICULTY:??Bloom's: UnderstandREFERENCES:??4.4 Introducting ProkaryotesLEARNING?OBJECTIVES:??UDOL.STES.16.4.5 - Demonstrate the structural similarities shared by bacteria and archaea using a diagram.105.?Chart the path of molecules of a secreted protein beginning at the DNA for a eukaryote.ANSWER:??The DNA message on the gene would be converted to RNA in the nucleus.? The RNA would leave the nucleus and travel to the rough endoplasmic reticulum.? At this point it would bind to a ribosome for translation to protein. The protein would leave the rough ER in a vesicle, travel to the Golgi apparatus for sorting, and then put in a new vesicle. This vesicle would travel to the cell membrane to be secreted.DIFFICULTY:??Bloom's: UnderstandREFERENCES:??4.7 The Endomembrane SystemLEARNING?OBJECTIVES:??UDOL.STES.16.4.9 - Examine the importance of the endomembrane system in a eukaryotic cell.106.?What are the properties of life?ANSWER:??Life makes and uses organic molecules, and is made of one or more cells. Life engages in metabolism to maintain homeostasis and to hydrolyze and synthesize molecules. Life grows, matures and ages - and thus is in constant change. And while DNA serves as the molecule of heredity to keep life similar from one generation to the next, life can change and evolve.DIFFICULTY:??Bloom's: UnderstandREFERENCES:??4.12 The Nature of LifeLEARNING?OBJECTIVES:??UDOL.STES.16.4.14 - Examine the properties that are unique to living organisms. ................
