The endoplasmic reticulum is a network of tubes and sacs that play an important role in the processing and secretion of proteins. There are two types of endoplasmic reticulum- smooth and rough. The difference between these two types is the appearance of their outer surface. The smooth endoplasmic reticulum has a smooth surface, whereas the rough endoplasmic reticulum has ribosomes on its surface. This article will discuss the differences between these two types of endoplasmic reticulum.
What is Smooth Endoplasmic Reticulum?
The Smooth Endoplasmic Reticulum (SER) is a type of organelle found in eukaryotic cells. Unlike the Rough Endoplasmic Reticulum (RER), the SER does not have ribosomes attached to its surface. This difference is due to the fact that the SER is involved in different cellular functions than the RER. The SER is responsible for lipid and carbohydrate metabolism, detoxification, and calcium storage. In contrast, the RER is responsible for protein synthesis and secretion. The SER is also Smooth because it lacks the rough appearance of the RER, which is due to the presence of ribosomes.
What is Rough Endoplasmic Reticulum?
The smooth endoplasmic reticulum (SER) is a type of organelle found in eukaryotic cells. SER plays an important role in the synthesis and transport of lipids and other molecules. It is also involved in detoxification and calcium ion homeostasis. SER appears smooth when viewed under a microscope, due to the lack of ribosomes on its surface. SER is found in all types of cells, but its abundance varies depending on the cell type. For example, SER is more abundant in liver cells than in other types of cells. Smooth endoplasmic reticulum was first discovered in 1873 by German biologist Eduard Oscar Schmidt.

Conclusion
The difference between smooth and rough endoplasmic reticulum is an important distinction to understand for anyone working in a biology-related field. However, it can also be helpful for those who are not experts in the topic to gain some understanding of these two types of organelles.
