Carrot slices placed in 0.2M salt solution for several hours becomes flaccid (limp). Carrot slices placed in freshwater for several hours becomes turgid (stiff). From this, we can deduce that the

1. freshwater is hypertonic and the salt solution is hypotonic to the cells of the carrot slices.
2. freshwater and salt solution are both hypotonic to the cells of the carrot slices.
3. freshwater is isotonic and the salt solution is hypertonic to the cells of the carrot slices.
4. freshwater is hypotonic and the salt solution is hypertonic to the cells of the carrot slices.
5. freshwater and the salt solution are both hypertonic to the cells of the carrot slices.
