Endomembrane System Set of related internal membranes that divide the cell into compartments Have same “common” membrane ancestor. Through evolution many membranes derived from the same one. These membranes are so similar that they are either directly connected to one another and/or are able to fuse portions of a membrane from another “related” organelle into their own.
