How do vacuoles help maintain homeostasis?

Vacuoles are organelles found in cells.
They play a role in storage of both nutrients and waste products .
They help maintain homeostasis in the following way:
- Maintaining acidity :
In case the pH in the environment drops a lot (becomes very acidic), there is a flux of H ions from the cell's cytoplasm into the cell's vacuole thereby increasing acidity to required level and thus maintaining the specific pH in the cells internal environment as well. - Turgidity
Vacuoles regulate the turgidity by regulating the amount of water inside the cell.
cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell.
cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity.
