Endoplasmic Reticulum (ER):
The endoplasmic reticulum (ER) is a network of membranes found in eukaryotic cells. It is responsible for various important functions such as protein synthesis, lipid metabolism, and detoxification of drugs.

Rough Endoplasmic Reticulum (RER):
- The rough endoplasmic reticulum (RER) is so named because it is studded with ribosomes on its surface.
- These ribosomes are responsible for protein synthesis, as they translate mRNA into proteins that are then transported into the ER lumen for further processing and modification.
- The RER plays a crucial role in the production of membrane proteins and secretory proteins.

Smooth Endoplasmic Reticulum (SER):
- The smooth endoplasmic reticulum (SER) lacks ribosomes on its surface, hence the name "smooth."
- It is involved in lipid metabolism, including the synthesis of lipids, phospholipids, and steroids.
- The SER also plays a role in detoxification processes, where it helps in the breakdown of harmful substances such as drugs and toxins.
In conclusion, the presence or absence of ribosomes on the surface of the endoplasmic reticulum distinguishes between the rough and smooth ER. While the rough ER is involved in protein synthesis, the smooth ER is involved in lipid metabolism and detoxification processes. Both types of ER are essential for the proper functioning of the cell.

Similar Class 9 Doubts

Read the text carefully and answer the questions:Cell organelles are enclosed by membranes. Cell organelles are the endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria and plastids. The endoplasmic reticulum (ER) is a large network of membrane-bound tubes and sheets. It looks like long tubules or round or oblong bags. There are two types of ER rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). RER looks rough under a microscope because it has particles called ribosomes attached to its surface. The ribosomes, which are present in all active cells, are the sites of protein manufacture. The Golgi apparatus, first described by Camillo Golgi, consists of a system of membrane-bound vesicles arranged approximately parallel to each other in stacks called cisterns.Q.Which of the given are covered by a single membrane?
