Which of the following are NOT considered as part of the endomembrane system? A. Mitochondria B. Endoplasmic reticulum C. Chloroplast D. Golgi Complex E. Peroxisomes NEET 2023
The organelles that are included in the endomembrane system are: NEET 2021
Answer & NCERT explanation
Correct answer: D — B, C and D only
Endomembrane system does NOT include mitochondria (A wrong). Mitochondria are double-membrane bound, not single (E wrong). B, C and D correctly describe organelle features.

The endomembrane system include endoplasmic reticulum (ER), golgi complex, lysosomes and vacuoles. Since the functions of the mitochondria, chloroplast and peroxisomes are not coordinated with the above components, these are not considered as part of the endomembrane system.
The endomembrane system includes ER, Golgi complex, lysosomes, and vacuoles—all organelles whose functions are coordinated. NTA frequently tests whether students can distinguish these from mitochondria, chloroplasts, and peroxisomes, which operate independently. The main trap is assuming all membrane-bound organelles belong to the endomembrane system; students often incorrectly include mitochondria or chloroplasts. The key to remember: endomembrane components work together in coordinated pathways (like protein synthesis and transport), while mitochondria and chloroplasts function autonomously with their own membranes and processes. Practice identifying which organelles participate in the secretory pathway versus those that don't.
