More than 3.4 million people die each year from water, sanitation, and hygiene-related causes.

Contractile vacuole helps to prevent lysis in many single-celled protists by regulating the water content within the cell. It accumulates excess water and then expels it from the cell, helping to maintain the cell's osmotic balance in a fresh water environment.
If a cell containing many dissolved solutes is placed in pure water, water would move into the cell through osmosis. This occurs because the concentration of solutes inside the cell is higher than in the surrounding water, causing water to flow in to balance the solute concentrations. As a result, the cell may swell and potentially burst if the influx of water is excessive. This process highlights the importance of osmotic balance in maintaining cell integrity.

If a cell is placed in salt water, water leaves the cell by osmosis.
If a cell is placed in salt water, water leaves the cell by osmosis.
Water would enter the cell via osmosis and it would finally burst.
The cell would undergo osmosis, which is the movement of water from an area of high concentration (pure water outside the cell) to an area of low concentration (inside the cell with dissolved solutes). This would cause the cell to swell and potentially burst if the water influx is too rapid.
Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
If a cell containing many dissolved solutes is placed in pure water, water will move into the cell through osmosis, as it moves from an area of lower solute concentration (the pure water) to an area of higher solute concentration (inside the cell). This influx of water can cause the cell to swell and potentially burst (lyse) if the osmotic pressure becomes too great. This process is critical for understanding how cells maintain their integrity and function in different environments.
The contractile vacuole helps it to get rid off the excess water from the cell.
