Vacuole ( Large ): Vacuole, in science, a space inside a cell that is vacant of cytoplasm, fixed with a film, and loaded with liquid. Particularly in protozoa, vacuoles are cytoplasmic organs (organelles), performing capacities, for example, stockpiling, ingestion, processing, discharge, and removal of overabundance water. The extensive focal vacuoles frequently found in plant cells empower them to achieve a substantial size without aggregating the mass that would make digestion challenges. ( Britannica 1 )
