In this video, we look at osmosis and water potential. First we look at how osmosis is simply the diffusion of water. We then look at what is meant by water potential and how we can define osmosis in terms of water potential.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
