One of the key innovations in the evolution of eukaryotes from a prokaryotic ancestor is the endomembrane system. which eukaryotic organelles or features might have evolved as a part of, or as an elaboration of, the endomembrane system?

The correct answer is A nuclear envelope. Endomembrane system is a group of membranes and organelles in a eukaryotic cell that works together to modify, package and transport lipids and proteins. The organelles include lysosomes, nuclear envelope and the endoplasmic reticulum, golgi apparatus, vesicles and plasma membranes. Nuclear envelope also the nuclear membrane is a lipid bilayer that surrounds the nuclear material and the nucleolus in eukaryotic cells
