Which of the following are NOT considered as the part of endomembrane system? A. Mitochondria B. Endoplasmic Reticulum C. Chloroplasts D. Golgi complex E. Peroxisomes Choose the most appropriate answer from the options given below:
Answer: (B) A, C and E only. Answer: (B) A, C and E only Solution: The endomembrane system includes only ER, Golgi complex, lysosomes and vacuoles.
- A.B and D only
- B.A, C and E only✓
- C.A and D only
- D.A, D and E only
Correct Answer
(B) A, C and E only
Solution & Explanation
Answer: (B) A, C and E only Solution: The endomembrane system includes only ER, Golgi complex, lysosomes and vacuoles. Mitochondria (A), chloroplasts (C) and peroxisomes (E) are NOT part of it because their functions are not coordinated with these components. ER (B) and Golgi complex (D) ARE part of the system, so the items NOT included are A, C and E, i.e. option (b). NCERT Reference: Ch 8, p.95, lines 15-20: "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."
