Osmosis

Definition

Osmosis is the movement of water molecules from hight to low water concentration (or low to high solvent concentration) through a partially permeable membrane.

GCSE biology uses this principle in studying how life works to such an extent that many post GCSE students continue to believe it is not only the reason for, but also the meaning of life.

At A Level this definition changes to "The net movement of water from a less negative water potential to a more negative water potential across a partially permeable membrane."

I'll never forget that as long as I live."

Fuller: "And what is this process called?" (one that blatantly isn't osmosis)

Student: "Osmosis?"

Fuller: (mouths) "F*** off"
