Rough endoplasmic reticulum
The RER consists of flattened, interconnected membranous sacs (cisterns) continuous with the nuclear envelope. RER possesses ribosomes on the cytoplasmic surface of the membrane. Proteins synthesized by the RER accumulate within the cisterns and are transported, via transport vesicles, to the Golgi for processing and packaging. 58,000x
