Why Strawberries bleed
« on: May 27, 2009, 11:40:48 PM »
Question: Explain why strawberries "bleed" when you put sugar on them.

I am thinking that it has to do with osmosis and that the sugar forms a solution on the surface of the strawberry, than the inside of the strawberry is less concentrated with this solution so the solution that formed on the surface is absorbed and the strawberry gets expanded pushing some juices out which i think he means by "bleed".

I might be thinking totally wrong so someone please help me...

Close but not entirely right. If the solution already formed on the outside, it desn't have to be absorbed. Think where did the juice in the solution on the outside came from.

I think i i got it. The solution that formed outside the strawberry is more concentrated than the sugar solution inside the strawberry. So the solvent or what we will call the "blood" is attracted to the higher concentrated solution and passes through the membrane of the strawberry to make both inside and outside isotonic. That is why the strawberries bleed.
