Eukaryotic cells have evolved an endomembrane system, containing membrane-bound organelles involved in transport. These include vesicles, the endoplasmic reticulum, and the Golgi apparatus. The smooth endoplasmic reticulum plays a role in lipid biosynthesis, carbohydrate metabolism, and detoxification of toxic compounds.
Endosymbiotic Theory of Evolution of Eukaryotic Cells. Diagram of a chloroplast. Diagram of a mitochondrion. THE THEORY: The mitochondria and chloroplasts of Eukaryotic cells arose from the symbiotic incorporation of prokaryotic cells by a proto-eukaryotic cell.ukaryotic cells originated more than 0.6 billion years ago. The mitochondria (and plastids) of extant eukaryotic cells are remarkably similar suggesting aerobic bacteria (or cyanobacteria) were incorporated on only one occasion each.
