@uybxaguui386: As you can see in this video, exposing plant cells to salt water will dehydrate the cells. This is an example of osmosis in action! Putting the onion tissue in distilled water means exposing the onion cells to a hypotonic solution. By osmosis, water molecules move from higher concentration to lower concentration. Thus, water moves from the outside to the inside of the cells. This causes the plant cells to swell, but the cell wall prevents them from bursting, therefore the cells will become as full of water as they can be. If they didn’t have a cell wall, the cells would swell so much that they would burst (this is what happens to animal cells when they are placed in distilled water).
