Osmosis is considered one of the most important biological processes that occur in living organisms, as it helps regulate the balance of water and salts inside cells. Since cells are the smallest units of life, osmosis plays a crucial role in the life of living organisms.

The Concept of Osmosis

Osmosis is characterized by the transfer of water from an area of lower concentration to an area of higher concentration of dissolved substances, through a semi-permeable membrane that separates two solutions with different concentrations of dissolved substances. When there is a concentration difference between the solutions, water moves from the area of lower concentration to the area of higher concentration until equilibrium is reached.

Practical Applications of Osmosis

The osmotic property is used in many practical applications, including:

- Water desalination: Osmosis is used in desalination of salty and polluted water, where water is passed through a semi-permeable membrane that separates the salts and impurities, resulting in purified and desalinated water.

- Sewage treatment: Osmosis is used in treating sewage water, where a semi-permeable membrane is used to separate the water from the solid, gaseous, and bacterial matter present in it.

- Cellular storage and feeding: Living cells use osmosis to regulate the balance of water and salts inside them, to maintain their natural biological activity.

- Plant feeding: Osmosis is used in the process of plant feeding, where water and nutrients are transferred from the soil to the plant through the root cells.

In conclusion, the osmotic property is one of the fundamental biological processes in living organisms, as it helps regulate the balance of water and salts inside cells and is used in many practical applications, including water desalination, sewage treatment, and plant feeding.
