Endoplasmic Reticulum Structure — NEET Biology
✅ Asked in NEET 2022Electron microscopic studies of eukaryotic cells reveal the presence of a network or reticulum of tiny tubular structures scattered in the cytoplasm that is called the endoplasmic reticulum (ER). Hence, ER divides the intracellular space into two distinct compartments, i.e., luminal (inside ER) and extra luminal (cytoplasm) compartments.
The ER is a membrane-bound network of tubules unique to eukaryotic cells, absent in prokaryotes. It divides the cell into two compartments: luminal space (inside ER) and extra-luminal space (cytoplasm). Students commonly confuse prokaryotes as having ER-like structures, which is incorrect. Remember: ER is a defining characteristic of eukaryotic cells only. NTA tests this to verify understanding of eukaryotic cell organization and compartmentalization, and to distinguish eukaryotic complexity from prokaryotic simplicity—fundamental concepts in cell biology.
Which of the following statements with respect to the endoplasmic reticulum is incorrect? NEET 2022 Phase 1
