What is the relevance of osmosis to cellular homeostasis?

Osmosis maintains the cellular homeostasis as this allows the exchange of water and other molecules into and out of the cell.

Explanation:

Osmosis may be defined as the solute particles movement from the  higher concentration region towards the region of lower concentration through the semi-permeable membrane.

Osmosis is helpful in maintaining the cellular homeostasis. Osmosis balance the ions and water molecules into and out of the cell. Only some selected particles can enter in the cell by the process of osmosis. Electrolytes balance in organisms can be performed by the process of osmosis as it allows the exchange of ions.
