What happens to the cells of a lettuce leaf after you add dressing to it?

It wilts because dressings are typically more concentrated than the cells of the lettuce, putting dressing on ahead of time will cause the lettuce cells to lose water because of osmosis. the water will tend to want to LEAVE the cell to go to equillibrium.

How do you explain what happen to the cells in a lettuce leaf when the dressing is added?
The cell wall is a semi-permeable membrane, allowing solvent (water) to passthrough but not solute (salts). When salad dressing is placed in contactwith the cells, osmosis occurs. If the salad dressing, in comparison to thecontents of the cell, is more concentrated, then water will leave the cell(causing the leafy salad to appear wilted). If the salad dressing, incomparison to the contents of the cell, is less concentrated, then waterfrom the dressing will enter the cell - perhaps causing cell rupture. Idoubt the second case truly happens, but you get the idea of what happensunder osmosis conditions.
What does tap water do to lettuce?
If you put the lettuce in fresh water there are more salts in the leaf than in the water, so the water will move back into the cells and make them rigid again, because the cells will swell. So if your lettuce in limp, laying it in water will make it crisp again.
