Raisin imbibes water and swells up. Imbibition is actually absorption of water as raisins are dry, they take up water from hypotonic solution .
if we place the raisins in an isotonic solution , there will be surely no change in the size as the cell wall is not a permeable membrane.

Yes, but it is the water that makes them do so not the sugar
Yes, it is a normal phenomenon.
Dried raisins absorb easily water and swell.
Hypotonic. If the solution had a lesser salt concentration, the cell would suck in more water to even out the salt levels inside vs outside the cell in the solution... it would suck in water, which would cause it to swell up.

In a hypotonic solution like distilled water the onion cell would "swell up" and the cytoplasm expands and water diffuses into the cell
If place in a hypertonic solution it would swell and/or burst because to much water is getting in the cell from the hypertonic solution ( osmosis ). If placed in a hypotonic solution it will end up shrinking from the water leaving the cell to the hypotonic solution ( again osmosis ). Osmosis is when water moves to a lower pressure of water so if there's more water pressure in the cell it will move out into the less dense solution. :)
A hypotonic solution would.
When a cell is placed in a Hypotonic solution, the water diffuses into the cell, causing the cell to swell and possibly explode.
If cells are placed in a hypotonic solution the cells gain water. The hypotonic solution has lower solute concentration then the cell's cytoplasm so the water will enter via osmosis.
vinegar is a hypotonic solution if you would like an example take an egg and put it in to a glass of vinegar and the egg will swell.
The organism would swell and then burst.

A hypotonic infusion will cause (all) the cells to swell. If they swell enough, they burst.
Swell and possibly burst depending on how hypotonic the solution was and how much of it was injected. However the human body has evolved many simple and complex ways to deal with these situations and therefore a small amount of hypotonic solution will likely cause no effect to your cells.
The solution would be a hypotonic solution.
