Detailed explanation-1: -The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.

Detailed explanation-2: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-3: -The two classes of endoplasmic reticulum are: smooth and rough. Rough Endoplasmic Reticulum (RER): It is a cell organelle that participates in the synthesis of enzymes and proteins. Smooth Endoplasmic Reticulum (SER): It is a cell organelle that Synthesises glycogen, lipids, and steroids.

Detailed explanation-4: -As discussed below, there are two distinct types of ER that perform different functions within the cell. The rough ER, which is covered by ribosomes on its outer surface, functions in protein processing. The smooth ER is not associated with ribosomes and is involved in lipid, rather than protein, metabolism.
