A wilted flower placed in a vase of water for several hours became stiff and stood erect. When it was placed in a salt solution, it wilted. From this information what can we say about the cells of the flower? A) the flower cells are hypertonic to fresh water but hypotonic to the salt solution. B) the flower cells are hypotonic to the fresh water and hypertonic to the salt solution. C) the flower cells are hypertonic to both the fresh water and the salt solution. D) the flower cells are isotonic to both the fresh and salt water solutions

Option A

Explanation:

The flower cells are hypertonic to fresh water but hypotonic to the salt solution.

Flower cell is hypertonic to fresh water, this means that the amount of solute in the solution outside the flower cell is higher than the solute content inside the flower cell.

While when a flower cell is hypotonic, it means that the amount of solute in the solution outside the flower cell is lower than the solute content inside the flower cell.

This is the reason why a flower plant placed in vase of water stood and become erect, while the same flower placed in a salt solution wilted.

Hence, option A is correct
