Answer: (D) Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles. Answer: (D) Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles Solution: The endomembrane system comprises the endoplasmic reticulum, Golgi complex, lysosomes and vacuoles, whose functions are coordinated.
- A.Golgi complex, Mitochondria, Ribosomes and Lysosomes
- B.Golgi complex, Endoplasmic reticulum, Mitochondria and Lysosomes
- C.Endoplasmic reticulum, Mitochondria, Ribosomes and Lysosomes
- D.Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles✓
Correct Answer
(D) Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles
Solution & Explanation
Answer: (D) Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles Solution: The endomembrane system comprises the endoplasmic reticulum, Golgi complex, lysosomes and vacuoles, whose functions are coordinated. Mitochondria, chloroplasts and peroxisomes are explicitly excluded because their functions are not coordinated with these components. Therefore only option (d) lists exclusively endomembrane organelles; all other options wrongly include mitochondria or ribosomes. NCERT Reference: Ch 8, p.95, lines 14-20: "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."
