Question

How do vacuoles help maintain homeostasis?

Answer 1

Hint: The vacuoles of plant cells are known to be multifunctional organelles that are central to cellular strategies of plant development. They share few basic properties with the vacuoles of algae and yeast and the lysosomes of animal cells.

Complete answer:
Vacuoles are organelles that are found in cells They are lytic compartments, function as the reservoirs for ions and metabolites, including pigments, and are necessary for processes of detoxification and general cell homeostasis
They play a vital role in the storage of both nutrients and waste products. They help to maintain homeostasis in the following way:
-Maintaining acidity: In some cases, 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 the acidity to the required level and thus maintaining the specific pH in the internal environment of the cell as well.
-Turgidity: Vacuoles regulate the turgidity by regulating the amount of water present inside the cell. the cell has excessive water: vacuole usually absorbs the water and then diffuses it out of the cell.
-cell lacks water: water from the vacuole tends to revert into the cell thereby maintaining turgidity.

Note: The vacuole plays a vital role in the homeostasis of the plant cell. It involves the control of cell volume and cell turgor; the regulation of cytoplasmic ions and pH; the storage of amino acids, sugars, and Carbon dioxide; and the management of toxic ions and xenobiotics.
