When electron micrographs were first taken of the cell interior, all of these membranous structures were seen. Membrane-bound vesicles of varying diameter containing material of different electron density were seen. Long channels bounded by membranes and radiating through the cytoplasm were observed. An interconnected network of canals was also visible, along with stacks of flattened, membrane-bound sacs called cisternae.
