Which of the following is used in water purification?

Turgor pressure is exerted by fluid in a cell that presses the cell membrane against the cell wall.

Fungi, protists, bacteria, and plants all secrete various extracellular molecules form together to create a solid wall on the outside of their cells. As water fills the cells, it pushes against the cell membrane and cell wall, producing turgor pressure.

It is a process where a weaker saline solution will tend to migrate to a strong saline solution.

Examples of osmosis are when plant roots absorb water from the soil and our kidneys absorb water from our blood.

It is also known as osmotic lysis, which occurs when a cell bursts and releases its contents into the extracellular body due to a large influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume.
