Explanation:

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