The main difference between Smooth ER and Rough ER: Smooth and rough endoplasmic reticulum are two types of ER that differ in their appearance and functions. Smooth ER lacks ribosomes and synthesizes lipids
Smooth ER vs Rough ER — Comparison Table
| Basis | Smooth ER | Rough ER |
|---|---|---|
| Ribosome Presence | No ribosomes | Has ribosomes |
| Appearance | Smooth surface | Bumpy or granular surface |
| Primary Function | Lipid synthesis and detoxification | Protein synthesis |
| Connected To | Not connected to nuclear envelope | Connected to nuclear envelope |
| Location | Scattered throughout cytoplasm | Near nuclear envelope |
| Product Movement | Lipids stored or used in membrane | Proteins move to Golgi apparatus |
| Abundance in Cells | High in liver and muscle cells | High in protein-secreting cells |
Key Points
- Smooth ER makes lipids; rough ER makes proteins
- Rough ER appearance bumpy due to ribosomes; smooth ER is smooth
- Rough ER protein products go to Golgi; smooth ER products stay in cell or membrane
- Both connected in cellular network allowing transport between organelles
