Vacuole | Definition, Structure, Function, & Facts | Britannica
WEBMar 20, 2024 · Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs, performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
Vacuole - Wikipedia
WEBVacuoles are essentially enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution, though in certain cases they may contain solids which have been engulfed. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.

WEBApr 29, 2024 · A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
5.11: Vesicles and Vacuoles, Lysosomes, and Peroxisomes
WEBVesicles and vacuoles are membrane-bound sacs that function in storage and transport. Vacuoles are somewhat larger than vesicles, and the membrane of a vacuole does not fuse with the membranes of other cellular components. Vesicles can fuse with other membranes within the cell system ( Figure 5.11.1 5.11. 1 ).
