Osmosis is the movement of solvent particles from their region of higher concentration to their region of lower concentration through a SEMI PERMEABLE LIVING MEMBRANE.
Like, root cells of plants absorb water through osmosis.
Raisins consist of dead cells, but they still have their cell wall. The cell wall, made of cellulose, attracts water molecules. So, raisins absorb water through the phenomenon of imbibition, or absorbtion due to cohesion between particles.
