Cell Membrane (Q1) (Q2) (Q3) NBpg. 63 Slide 1 of 2 Cell Membrane Page 8 EQ: Describe how the cell membrane is like a fluid mosaic model. (Q1) Structure: All cells are surrounded by a thin, flexible barrier known as the cell membrane; known as a lipid bilayer with embedded structures. Function: Provide protection and support, but more importantly regulates movement of molecules that enters and leaves the cell; known as selectively permeable. What can pass: Small, non polar molecules like gases What cannot pass: Large, polar molecules (Q2) (Q3)
