Biology 1001 MUN Section 3 Questions and Answers Rated A+ **1. What is the role of the plasma membrane in a cell?** - The plasma membrane acts as the outer living layer of each cell, serving as a gatekeeper that separates the external environment from the cell's interior. **2. What does the term "amphipathic" refer to?** - It describes molecules that have both hydrophilic (water-attracting) and hydrophobic (water-repelling) components. **3. What factors influence membrane fl...
