Description: Forming membrane-bound cytoplasmic compartments in many eukaryotic cells, vacuoles vary widely in size, number and function. Plant cells contain large vacuoles that can store water and help maintain hydrostatic pressure.the quick recovery of a wilted plant when watered is due to the filling of water vacuoles in the cells. Fungal cells and some bacteria also have vacuoles, which can function in storage of a wide range of ions as well as water balance. Cells with vacuoles have relatively less cytoplasm, and the presence of a large central vacuole can push organelles towards the periphery of the cell. In those animal cells that have vacuoles they are used for water, food and waste storage. Vacuoles are formed by the fusion of smaller vesicles.
