Annette observed that if she put salad dressing on her salad in the morning before leaving home, by lunch time she found excess
liquid in her container and the greens were wilted. Why does this happen? A) Condensation from the refrigerator accumulates in the salad container. B) The dressing creates a hypertonic solution around plant cells, which causes water to diffuse out of the cell plasmolysing the cells. C) The dressing creates an isotonic solution around plant cells, which causes water to diffuse into and out of the plant cells making them flaccid. D) The dressing creates a hypotonic solution around plant cells, which causes water to diffuse into the cell creating an increase in turgor pressure
When the salad is fresh without dressing then the environment outside the plant cell and inside is isotonic.
As soon as the dressing is put over the salad then after sometime the dressing creates an hypertonic environment around the plant cell and water comes out of the plant cell (salad) as a result of plasmolysis.
