Solution:

In the given system, Solvent molecules will flow continuously until equilibrium is attained.
The flow of solvent from the solvent side to solution side across the semi-permeable membrane can be stopped if some extra pressure (osmotic pressure) is applied to the solution.
Osmotic pressure is the minimum external pressure that must be applied on solution to prevent osmosis.

Osmotic pressure.
