How do vacuoles help maintain homeostasis?

Answer 1

Penelope Adams

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.

Vacuoles contribute to cell stability and internal condition balancing by regulating turgor pressure, storing nutrients and waste products, and maintaining an acidic pH level.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
