When fruits and vegetables are dried and placed in water they slowly swell and return to their original shape why?

When fruits and vegetables are dried, the water content is significantly reduced, causing them to shrink and lose their original shape. When these dried items are placed in water, osmosis occurs, allowing water to re-enter the plant cells. This rehydration process causes the cells to swell and regain their original structure, as the cell walls expand to accommodate the absorbed water.
