Correct Answer: A
Solution :
[a] Tonoplast is a membrane separating a vacuole from the surrounding cytoplasm in a plant cell. It controls ionic movement in and around the cell. Contractile vacuole is a sub-cellular structure found in unicellular algae. It absorbs excess water and wastes from a microorganism's cell and excretes them into the environment. Food vaculole is a membrane-unclosed cell vacuole with a digestive function. It contains material taken up in by the process of phagocytosis. Air vacuole is a small cavity or space in the tissues. It stores metabolic gases.
