Osmosis is integral to life. A change in the surrounding enviroment could disrupte the homeostasis of a cell.

This Jazz Cabbage got me zooted. Jazz Cabbage is less harmful than Squares. I’m smoking that Jazz Cabbage boy.

Student #1: Dude, I'm soooo tired and stressed about tomorrow's test, I'm soooo unprepared.

Student #2: Dude, relax. You can kill 2 birds with 1 stone, just use osmosis.

As Pamelas life got dull she chose better living thru osmosis.

It was through osmosis that I learned about this blatantly undesirable video game.

Imagine a tea bag, the bags walls are porous (holes in them) just like a membrane.

The water displaces inside the bag, now although this has a lot to do with environmental pressure (ie. the water) it is mostly to do with diffusion, Osmosis is a form of diffusion*, specifically across a semi - permeable (porous) membrane.

*

Diffusion is displacement of molecules so that they are equal.

E.g. Imagine your friend sprays deodorant/perfume on the far side of the room, it takes a couple of seconds to reach you.
It is a highly concentrated cloud at first but then spreads (diffuses) into the air until there are an EQUAL concentration of spray to the air.

E.g. five 1 pennies to every three 2 pennies

I only passed that test because I got the knowledge through osmosis from my friends
