WebThere are two types of ER: rough ER and smooth ER. The outer side (facing the cytosol) of the rough ER is studded with ribosomes. Under the electron microscope, the dense granular ribosomes gave the name of “rough” ER. Rough ER stays closer to the nucleus and coordinates protein synthesis. Smooth ER lacks ribosomes.
