Solution
Locomotion
Explanation -
Vacuoles are single membrane-bound, fluid-filled sacs present in the cytoplasm. Vacuoles are meant for the storage of food, water and other substances. In plant cells, vacuoles are full of cell sap and provide turgidity and rigidity to the cell. In single-celled organisms like Amoeba, the food vacuole contains the food items that the Amoeba has consumed. In some unicellular organisms, specialised vacuoles also play important roles in expelling excess water and some wastes from the cell (osmoregulation).
