A vacuole, in biology, is 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.
Plant cell structure Animal cell structure A vacuole (/ ˈvækjuːoʊl /) is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells. [1][2] Vacuoles 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 ...
The vacuole is a membrane-bound organelle found in many types of cells. While the organelle is especially prominent in plants and fungi, animal and protist cells also contain vacuoles. It plays essential roles in maintaining cell structure, storing nutrients and waste, degrading substances, and regulating pressure and pH within the cell. Although the term “vacuole” evokes the image of an ...
Vacuole in plants and fungal cells perform similar functions in some ways. Thoughit mainly acts as a water reservoir, it also stores some small molecules, such as polyphosphate, amino acids, several ions, and other small molecules.
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.

A vacuole is a sac-like organelle enclosed by a single membrane, known as the tonoplast in plant cells. This membrane, composed of a phospholipid bilayer with embedded proteins, separates the vacuolar contents from the cell’s cytoplasm.
