General Biology 101 Exam I: Lecture Outlines/Study questions Fall 2008 1 CELLULAR ORGANIZATION I. Biological organization What is the hierarchy of life in terms of cells, organ systems, organisms, tissues, organs, chemicals, and subcellular organelles? II. Cellular metabolism How do anabolism and catabolism contribute to metabolism ? What are the roles of hydrophilic and hydrophobic substances in living things? Why are minerals important? What is the importance of carbohydrates, lipids, proteins (especially enzymes ) and nucleic acids? III. Cellular functions What is the evolutionary significance of the Cell Theory ? Are viruses cellular? IV. Plasma membrane (Fig. 5-6) Is every cell enclosed by a plasma membrane ? Why? Does every cell have a cell wall ? V. Cell size (Fig. 4-2) What are the consequences of a cell’s surface-to-volume ratio ? How do we express the size of a cell or its subcellular constituents in SI units: meter ( m ); millimeter ( mm ), micrometer ( μm ), and nanometer ( nm )? VI. Prokaryotes and eukaryotes How do the cells of prokaryotes and eukaryotes compare in terms of evolutionary history , size, and organization? VII. Research tools used by cell biologists A. Microscopy (Figs. 4-3, 4-4) How do light microscopy , transmission electron microscopy (TEM) , and scanning electron microscopy (SEM) compare in terms of methods and applications, effective magnification , resolution , and contrast ?
