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.
A contractile vacuole is an organelle in single-celled organisms that helps the cell remove wastes and excess water. It is found primarily in freshwater protists and algae. They are necessary because, in fresh water, the concentration of solutes inside a cell is greater than that outside the cell, so the cell constantly absorbs water through osmosis. In Paramecia , a typical freshwater protist, the vacuole is encompassed by a few waterways, which ingest water by osmosis from the cytoplasm.
