Understanding Endoplasmic Reticulum (ER)
The endoplasmic reticulum (ER) is a vital organelle in eukaryotic cells, playing a key role in protein and lipid synthesis. Below is a breakdown of the statements regarding the ER:
Statement Analysis
- SER is devoid of ribosomes
- This statement is correct. The smooth endoplasmic reticulum (SER) does not have ribosomes attached to its surface, distinguishing it from the rough endoplasmic reticulum (RER).
- In prokaryotes only RER are present
- This statement is incorrect. Prokaryotes, such as bacteria, do not have membrane-bound organelles, including the endoplasmic reticulum. Only eukaryotes possess SER and RER.
- SER are the sites for lipid synthesis
- This statement is correct. The smooth ER is primarily involved in the synthesis of lipids, including phospholipids and cholesterol.
- RER has ribosomes attached to ER
- This statement is correct. The rough endoplasmic reticulum is characterized by the presence of ribosomes on its cytoplasmic surface, which are essential for protein synthesis.
Conclusion
In summary, the incorrect statement regarding the endoplasmic reticulum is that "In prokaryotes only RER are present," as prokaryotes lack both types of ER. This highlights the fundamental differences between prokaryotic and eukaryotic cells regarding cellular structures and functions.

Presence of membranous organelles is an exclusive property of eukaryotic cells. Endoplasmic reticulum is an example of membranous organelles, so, it will always be found in eukaryotic cells only and never in the prokaryotes. This is true for SER and RER both.
