This electron micrograph illustrates intracellular membranes, such as SER, RER and the two membranes of the nuclear envelope. Mitochondria are also composed of two membranes, though they cannot be readily distinguished at this magnification. Also visible is the connection between the nuclear envelope and the RER. 30,000x
