Solution

Osmosis
Osmosis takes place when water moves from a high-concentration area to a low-concentration one.
There are two forms of osmosis: endosmosis and exosmosis.
Placement of dried raisins in water and then in sugar solution
When raisins are placed in water, they will swell due to endosmosis.
Water with a higher concentration enters the raisins.
When raisins are placed in a sugar solution, they will shrink due to exosmosis.
Water from the raisins leaves the raisins and enters the outer medium because the concentration of water within the raisin is higher than the sugar water outside.

Q. A Student dissolved 5 g of sugar in 100 mL of distilled water in beaker A. He dissolved 100 g of sugar in 100 mL of distilled water in beaker B. Then he dropped a few raisins of equal weight in each beaker. After two hours he found the raisins in A swollen and those in B shrunken. The inference drown is that:
(1) sugar concentration of raisins is lower than that of solution A and higher than that solution B.
(2) sugar concentration of raisins is higher that that of solution A and lower that that of solution B.
(3) in B the cell membrane of raisins was damaged resulting in bleaching.
(4) in A the permeability of water of the cell membrane of raisins was enhanced
