Planning.
Osmosis is the diffusion of water molecules across a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration, to an area of low concentration. So, Osmosis is the movement of water molecules from an area where there are lots of water molecules to an area where there are few water molecules.
Our aim is to find the concentration of dissolved substances in the cells of a potato using Osmosis.
