The endoplasmic reticulum is a network that membranes that is present inside eukaryotic cells. This structures are responsible for the production and also transportation the proteins, fats and other important molecules compelled for the work of a cell.

Difference in between RER and SER


Although an important component the the cell, not every kind of cell has an absorbent reticulum, for instance, red blood cells execute not have an ER.

Cells the play crucial role in the manufacturing of proteins and also oils have huge amounts of ER. Structurally, there space two types of absorbent reticulum in a cell. Castle are:

Rough absorbent reticulumSmooth absorbent reticulum

Difference in between Smooth and Rough endoplasmic Reticulum

The most straightforward difference between RER and SER is the existence of ribosomes. When ribosomes connect to the surface of an ER, it offers a characteristic unstable appearance; hence it is referred to as Rough ER. On the other hand, a smooth ER go not have actually ribosomes ~ above its surface.

The other major differences between the smooth endoplasmic reticulum and rough endoplasmic reticulum room summarized below:


Rough absorbent Reticulum (RER)Smooth absorbent Reticulum (SER)
It possesses ribosomes attached to its membrane.It does not have ribosomes on its membrane.
Formed of cisternae and a few tubules.Formed that vesicles and also tubules.
It participates in the synthesis of enzymes and proteins.Synthesises glycogen, lipids and also steroids.
It help in the development of lysosomes.Gives climb to Spherosomes/ Oleosomes
It is internal and connected with the atom envelope.It is peripheral and may be connected to plasmalemma.
Ribophorins are present and assist ribosomes attach to ERDevoid that Ribophorins.
It might develop from the atom envelopeDevelops from unstable Endoplasmic Reticulum.
Provides proteins and lipids because that Golgi apparatus.Provides vesicles for cis-face of Golgi apparatus.

The most evident difference in between smooth and also rough endoplasmic reticulum is the presence of ribosomes. Only the unstable endoplasmic reticulum has actually ribosomes ~ above its surface, and that gives it that characteristic rough appearance.
