The nuclear envelope is a key feature of the endomembrane system. It is a double membrane that surrounds the nucleus and is continuous with the rough endoplasmic reticulum. The endomembrane system also includes the rough and smooth endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles. Chloroplasts and mitochondria evolved from endosymbiotic events and are not part of the endomembrane system. The plasma membrane is not an evolution of the endomembrane system but rather a separate structure that is present in both prokaryotes and eukaryotes.
