We have been workinging lately with osmosis, and we recently did a lab. It involved putting a piece of celery into different petri dishes, which had different solutions. Distilled water with salt, from 0 g/mL to 2. The less salt in the solution, the celery grew, and then at 1.2 it startes to shrink. A conclusion question we have to answer asks us why grocery store owners spray fresh fruits and vegetables with water. I always thought it was just to keep them fresh. But there must be something to do with the lab, and possibly osmosis. I have looked at many different sources for possible answers, and cannot figure it out. Help please?
