Going back to the basics of osmosis:

Water will move across a semi-permeable membrane from areas of higher concentration of salts and/or sugars to less concentrated areas. The “receiving” side of the semi-permeable membrane contains the highly concentrated sugar solution. Since this side of the membrane has a higher osmolarity then the side containing the salt water, the water (since the salt cannot cross the membrane) will pass through the membrane in an attempt to dilute the sugar solution.
