This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane, with holes only small enough for water molecules to pass through and not larger ones like glucose. An example of a partially permeable membrane is visking tubing. Osmosis happens so that the concentration outside the membrane is equal to the concentration inside the membrane...

Osmosis happens so that the concentration outside the membrane is equal to the concentration inside the membrane. This means that there will be a steady net flow into the stronger solution, (of glucose) causing this region to fill with water and dilute it. This is how the concentration is balanced. Higher water concentration means a more dilute solution; because water makes up a high proportion of the molecules present, conversely lower water concentration means a more concentrated solution...
