If you place a carrot in plain water, what would you expect to happen to the carrot overnight? Nothing, the carrot would stay the same. The carrot would shrink, because water would move out of the carrot cells. The carrot would grow because water would move into the carrot cells,

See the answer below

Explanation:

If a carrot is placed in plain water overnight, water will enter the cells of the carrot osmotically due to the fact that the cytosols of the cells of the carrot have higher concentration of solute than the surrounding plain water. As such, the cells will become turgid and the carrot would grow bigger in size compared to the previous night.
