If you add sugar to strawberries, they become "runny" and juice oozes out, why? what is going on?

Isn't that due to osmosis?

Strawberries are slightly acidic, aren't they? Then the sugar is reacting with the surface membrane (probably through osmosis)and perhaps breaking it down or in some other way making it permeable.

Just a thought. I don't know but I might as well act as if I do. Everyone else does!!!!!!!

Yes, it's osmosis. Water goes from regions of low concentration to regions of high concentration, when there's a 'semi - permeable membrane' like a cell membrane.
You will get the same effect if you cut a potato in half and scoop out a small hole in one half. If you put sugar (or sale) in the hole, you end up with a puddle of water. Not as nice to taste as the strawberry, though.
