Hi @Nekros,

Although there is nothing wrong with that statement on it's own, I think it's important to include keywords such as "partially permeable membrane". Just to be safe in an exam it could be helpful to memorise a more well rounded definition of Osmosis: the diffusion of water across a partially permeable membrane from a dilute solution (high water potential) to a concentrated solution (low water potential).

Hope this helps,

"the movement of water molecules through a semi-permeable membrane from an area of high concentration to low concentration" - osmosis

I would word it like this as I done Biology GCSE AQA and they can be picky with certain words
