Osmosis

Reverse osmosis desalinates fresh water from ocean salt water.

These large molecules pull water into the brain tissue after them by osmosis.

Just by osmosis. Nobody ever sits down and tells you, This is how it works.

As a result, water from other cells enter the guard cells by osmosis so they swell and become turgid.

This process will stop once the pressures of the water and sugar water on both sides of the membrane become equal (see osmosis).

Similarly, the founder of Côte d Ivoire, Félix Houphouët Boigny, coined the word Françafrique to underline the total osmosis between France and its former colonies.

Then I found out, post exposure, that this plastic bag if I put it into a filthy puddle or a stream filled with coliforms and all sorts of disgusting stuff, that that filthy water will migrate through the wall of the bag by osmosis and end up inside it as pure, potable drinking water.
