Explanation: 

Detailed explanation-1: -The RER is termed “rough” due ribosomal attachments to the surface compared to the SER, which does not have ribosomes.

Detailed explanation-2: -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.
