Show Hint
Contractile vacuole = Osmoregulation (Water balance).
Food vacuole = Phagocytosis (Nutrition).
Remembering this distinction helps avoid confusion in protist cellular anatomy.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests our understanding of eukaryotic organelles, specifically the endoplasmic reticulum, Golgi apparatus, and vacuolar systems.
Step 2: Key Concepts and Approach:
We systematically analyze the structural and functional descriptions of organelles in each statement.
Step 3: Detailed Explanation:
• Statement A: The network of tiny tubular structures of the Endoplasmic Reticulum (ER) divides the intracellular space into two distinct compartments: the luminal compartment (inside the ER tubules) and the extra-luminal compartment (cytoplasm outside the ER). This is structurally accurate and correct.
• Statement B: Camillo Golgi first observed densely stained reticulate structures near the nucleus, not close to the cell wall. Therefore, this statement is incorrect.
• Statement C: In Amoeba, the contractile vacuole is responsible for excretion and osmoregulation.
Food particles are engulfed by pseudopodia, forming food vacuoles. Thus, this statement is incorrect.
• Statement D: Proteins synthesized by ribosomes attached to the Rough Endoplasmic Reticulum (RER) are transferred to the Golgi apparatus.
Inside the Golgi cisternae, they undergo post-translational modifications (like glycosylation) to form glycoproteins. This statement is correct.
Step 4: Final Answer:
Statements A and D are correct, making option (C) the correct choice.
