Prokaryotic Cells: What Structures Are Present in All Cells? 1. Describe (or draw) the structure of the cell plasma membrane, indicating hydrophobic and hydrophilic regions; what are 3 ways in which proteins can be oriented within the membrane? 2. Indicate how (and why) each of the following is able cross the plasma membrane: a large, hydrophobic molecule a hydrophilic molecule a very small (non-ionic) molecule 3. Indicate 2 functions of membrane proteins that are not related to transport. 4. Indicate, in general terms, how each of the following contributes to genetic information within a cell and the conversion of this information into specific proteins. DNA RNA ribosomes 5. Describe the chromosome of prokaryotic cells, including its basic structure and location within the cell. 6. What is a bacterial plasmid and how does it differ from the main chromosome? 7. Distinguish between the terms "genome" and "proteome". 8. Be able to recognize the plasma membrane, nucleoid region, and ribosomes in an electron micrograph of a bacterial cell.
