Differentiate between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER).

Difference between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER) are as below

RER ( Rough Endoplasmic Reticulum)	SER ( Smooth Endoplasmic Reticulum)
1. RER Possesses ribosomes attached to its surface.	1. SER does not bear ribosomes attach to their surface.
2. Mainly formed of cisternae and few tubules.	2. Mainly formed of vesicles and the tubules.
3. RER takes place in the synthetics of proteins and enzymes.	3. SER takes place in the synthetics of glycogen, lipids and steroids.
4. RER is internal and connected with nuclear envelope.	4. SER is peripheral it may be connected with plasmalemma.
5. it may develop from the nuclear charge.	5. it may develop from RER.
6. Enzymes for deroxification are absent in RER.	6. it has the enzymes rise to sphaerosomes.
