BIO 101 Chapter 3: Unit 3
Document Summary
The following questions will act as a guide for your study of the cell. The chart must be completed thoroughly and handed in as the homework assignment for this unit (20 points). Your completed chart should cover the level of detail asked in the questions. 6. 1: differentiate between light and electron microscopy. Give the description and function of the following: cell wall, plasma membrane, bacterial chromosome, nucleoid region, cytoplasm, agella, and ribosome. a. cell. Wall: the rigid outside the plasma membrane structure. Explain the relationship of surface area to volume: eukaryotic cells are typically larger than prokaryotic cells. The smallest cells are mycoplasmas, which are a type of bacteria: only a limited amount of material can pass between a square micrometer of plasma membrane. Therefore, a larger surface area and smaller volume are more advantageous for cells: as a cell increases its size, its surface area grows proportionately less than its volume. 6. 3: look at the gure on page 103.
