Is homeostasis inside a cell organelle?

What is its function?

Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. The cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell. Cells also maintain a higher concentration of potassium ions and organic acids on their inside. The membrane also allows for water to be pumped in or out, which affects the concentration of the cytosol. Lastly, the fluidity of the membrane can be changed so that the cell can adjust to changing temperatures that might solidify its membrane.
