Answer:
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.
