Rough Endoplasmic Reticulum (ER) has ribosomes on it while smooth ER does not.
The reason it was named ROUGH ER is because it looks all bumpy ("rough") when viewed under a microscope (the bumps are the ribosomes).

First, The endoplasmic reticulum is called ¨rough¨, because at the electronic microscope image it looksas it hadrough edges. that is responsability of the rybosomes tached to it´s membrane.
This combination serves as a protein factory, specially when some are required in large cuantities to be packed and be exported( excreted from the cytoplasm to the inner medium, for example: gammaglobulyns).
Smooth endoplasmic reticulum has no rybosomes, and serves aas a complex lipid factory.

Named for the presence or absence of ribosomes ON the 'E.R,"
Rough E.R> appears that way thru the electron microscope because of the attached ribosomes. The opposite if true for smooth ER.

rER contain ribosomes on their surfaces, located conveniently for protein synthesis, then quick access to the ER for modification. Smooth ER do not have ribosomes on their surfaces.

I am pretty sure the rough endo. reticilum has ribosomes on it and the smooth doesn't.
