Question

Choose the correct statements among the following
A) Endoplasmic reticulum will divide the intracellular space as luminal and extra luminal compartments
B) Camillo Golgi observed densely stained reticulate structures close to the cell wall
C) In Amoeba contractile vacuole formed to engulf the food particle
D) Protein synthesised by ribosomes are modified in the cisternae of golgi apparatus

• A. A, B
• B. B, C
• C. A, D
• D. B, D

Hint:

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

Answer 1

The Correct Option is C

Step 1: Verify the ER statement.
The endoplasmic reticulum is a maze of tubules that genuinely splits the cell into a luminal space inside the tubules and an extra luminal space outside them in the cytoplasm, so statement A is accurate.
Step 2: Verify the ribosome and Golgi statement.
Proteins made by ribosomes on the rough ER travel to the Golgi apparatus, where the cisternae modify, package and sort them before they head to their final destination, so statement D is accurate too.
Step 3: Catch the two wrong statements.
Camillo Golgi actually spotted his reticulate structures near the nucleus, not near the cell wall, so statement B is wrong. And in Amoeba, it is the food vacuole that engulfs food particles, while the contractile vacuole is a separate structure whose job is pumping out excess water for osmoregulation, so statement C is also wrong.
Final answer: Option 3, statements A and D are correct while B and C are false.
