<em>The endomembrane system</em> includes the nuclear envelope, the <em>endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layer</em>
These cell parts cooperate to <em>alter, bundle, tag, and transport layer lipids and proteins </em>
The nuclear envelope is a double membrane, implying that there are <em>two lipid bilayers</em>
The nuclear lamina, a netlike cluster of <em>protein filaments, associates the layers of the nuclear envelope</em>
