Very small polar molecules like H2O Outside of a cell's membrane Ions like Na+ and Cl- Very large polar molecules like glucose and amino acids Nonpolar molecules like lipids, CO2, and oxygen Inside of a cell's membrane Figure 1. Selectively Permeable Cell Membrane Question 12: Observe Figure 1. What kinds of molecules are able to pass through the phospholipid bilayer membrane easily? What kinds of molecules are not able to pass through easily? What are the characteristics of each (charge, polar vs. nonpolar, and size)? Move easily Do not move easily Because water is a small and flat molecule (despite it being polar), it can either pass through the
