Dry raisins when put in water swell up because water is hypotonic and the raisin is hypertonic. Water moves from a higher concentration of water to a lower concentration of water that is from hypotonic to hypertonic.. Therefore the raisins will swell up...

dry raisins when placed in water swell up
===============================
REASON -
Rasins swell up due to endosmosis.
when dry rasins are placed in water, it has a low water concentrate or is less dilute from the surrounding water.
as a result of which water (high pressure ) travells inside the rasins (low pressure )through a semi permeable membrane . this continous inward movement of water swells up the rasins.
