Going by the diagrammatic illustration, the molecules would move into the cell until an equilibrium is reached.
Diffusion generally involves the movement of molecules from the region of higher concentration of a molecule to the region of lower concentration of the same molecule. The net movement will continue until both sides have equal concentrations of the molecule.
Looking at the diagram, there are more of the molecule outside the cell than inside of it. Thus, the molecules will keep moving inside the cell until both the outside and inside have the same concentration.
