- A.They lie free in the cytoplasm
- B.These represent reserve material in cytoplasm
- C.They are not bound by any membrane
- D.These are involved in ingestion of food particles✓
Correct Answer
(D) These are involved in ingestion of food particles
Solution & Explanation
Answer: (D) These are involved in ingestion of food particles Solution: Inclusion bodies are reserve materials stored in the cytoplasm of prokaryotic cells; they are not bound by any membrane and lie free in the cytoplasm. They have no role in ingestion of food particles (that is associated with phagocytic/food-vacuole activity), so statement D is not correct. Statements A, B and C correctly describe inclusion bodies. NCERT Reference: Ch 8, p.91, lines 27–30: "Reserve material in prokaryotic cells are stored in the cytoplasm in the form of inclusion bodies. These are not bound by any membrane system and lie free in the cytoplasm, e.g., phosphate granules, cyanophycean granules and glycogen granules."
