Prescott, Harley & Kliens Microbiology doesn't particularly have an exact definition, merely stating that during osmosis, water moves across a selectively permable membrane (such as the plasma membrane) from dilute solutions (high water concentrations) to more concentrated solutions (low water concentration).

From GCSE that's what I remember.

"Osmosis is the diffusion of water from a high concentration to a low concentration".

... across a partially permeable membrane.

is it just me or is osmosis the only thing anyone can remember from GCSE biology?

Needed to mention concentration gradient and partially permeable membrane when I did it.
