The Osmosis Process
Discussion:
Osmosis is a passive process by which water molecules move through a partially permeable membrane from a region of high concentration to a region of low concentration, creating an equal amount of molecules from both regions on each side of the membrane. This process is the result of a downhill energy system known as water potential. Water potential is the potential energy of water (per unit volume) that allows it to move from one area to another by osmosis. This system causes the water to freely move from an area of higher water potential (energy) to an area of lower water potential (energy). Osmosis is an on-going process, meaning that water constantly flows in both directions but the total movement of water is always in the direction from the higher concentration to the lower one. Even when the concentration of water is equal on both sides of the membrane, osmosis still continues at a slower rate to maintain the balance.
Osmosis in cells plays an essential role in biological life. Regulating osmosis is important for a cell’s survival because it maintains an optimal environment within that cell. Plant cells possess certain structures such as the cell membrane, the cell wall, the vacuole and the cytoplasm, which are involved in the process of osmosis.
In order to regulate osmosis, a cell uses a fluid mosaic of lipids, proteins, and carbohydrates known as the cell membrane. This structure also consists of a bilayer of phospholipids with the hydrophobic regions (tails) facing each other on the inside of the structure, and the hydrophilic regions (heads) facing outwards. Biological cell membranes are selectively permeable, meaning that they only allow the passage of certain molecules depending on their size and charge. Their role is to regulate the exchange of nutrients, oxygen, inorganic ions, waste products, and water moving in and out of cell so as to keep a constant environment within their cell. Water enters and leaves the cell based on its
