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 major function of the smooth endoplasmic reticulum is the detoxification of the body from drugs consumed and metabolic wastes produced. The major function of the rough endoplasmic reticulum is protein synthesis and their folding into proper quaternary structures.
Detailed explanation-3: -The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
