Homeostasis is regulating processes to keep something stable or constant. The cell membrane, found on the outside of the cell, controls what goes in and out of the cell. This makes sure that the cell is not introduced to any harmful materials that would create complications for the cell and its functions.
A cell membrane is the outer covering or skin of a cell that is the main controlling power of what will enter and what cannot enter in the cell.
The cell membrane helps cells maintain homeostasis by controlling the movement or activities regarding anything entering or leaving the cell.
Cell membrane plays an important role in maintaining the homeostasis by controlling the substances that penetrate the cell, either entering the cell, or leaving the cell.
Since the cell membrane is a phospholipid bilayer, it can control the transition of water and ions. If the lipid tails, found between the electrically charged phosphate sectors, become solid, the cells skill to control ion and water concentration is lost. This problem is solved by the cell by adding cholesterol to the membrane, while the lengths of lipid tails is shortened.
The volume of the cell is maintained due to the cell membrane which it diminish the speed of the water movement entering or leaving the cell.
The positively or negatively charged molecules cannot cross the cell membrane without specialized transport, hence, ions pass the cell membrane helped by the proteines used by the cell membrane.
Hence, the cell membrane actively controls the difussion of substances and the movement of ions and proteins.
