How does the plasma membrane maintain homeostasis?

The plasma membrane, also called the cell membrane or phospholipid bilayer, is the sack that surrounds cells. Homeostasis is a state of balanced equilibrium, where everything is running smoothly. read more

The plasma membrane also maintains homeostasis by making sure materials can move in or out as necessary. Homeostasis depends on maintaining correct fluid levels within the cell and on exchanging useable materials, such as oxygen, for waste products, such as carbon dioxide. read more

Maintaining those levels is the process of homeostasis -- a process essential for life. The plasma membrane does that by presenting a barrier to uncontrolled diffusion and actively controlling the movement of ions, nutrients and wastes and other proteins. read more

The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in. read more
