Question
Distinguish between smooth and rough endoplasmic reticulum.
Solution
| Character | Smooth endoplasmic reticulum (SER) | Rough Endoplasmic Reticulum (RER) |
| Definition | Smooth endoplasmic reticulum does not have ribosomes on its membrane. | Rough endoplasmic reticulum possesses ribosomes attached to its membrane. |
| Organized | It is organized of vesicles and tubules. | It is organized of cisternae and a few tubules. |
| Found | It is present near the cell membrane. | It is present near the cytoplasm. |
| Formation | SER gives rise to spherosomes/oleosomes. | RER helps in the formation of lysosomes. |
| Composed of | It is composed of the tubules. | It is composed of the cisternae. |
| Synthesis | Synthesises glycogen, lipids, and steroids. | It participates in the synthesis of enzymes and proteins. |
| Connection | SER may be connected to plasmalemma and is peripheral. | RER is connected with the nuclear envelope and is internal. |
| Development | Develops from Rough Endoplasmic Reticulum. | It might develop from the nuclear envelope. |
| Ribophorins | It lacks ribophorins. | It consists of ribophorins and helps ribosomes attach to ER |
| Provide | Provides vesicles for cis-face of the Golgi apparatus. | Provides proteins and lipids for the Golgi apparatus. |
| Produces | It produces lipids and proteins. | It produces proteins. |
