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

Answer:

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

Final answer:

The flower cells behave as hypertonic in fresh water, causing them to absorb water and stand erect, while they act as hypotonic in a salt solution, leading to water leaving the cells and wilting the flower.

Explanation:

From the information given about the flower's cells, the correct answer is A) the flower cells are hypertonic to fresh water but hypotonic to the salt solution. This is due to the process of osmosis, which is the movement of water across a semi-permeable membrane, like a cell wall, from areas of low solute concentration (hypotonic) to areas of high solute concentration (hypertonic).

When the wilted flower was placed in the fresh water, the cells were hypertonic causing water to enter the cells and making the flower stand erect. This is because there were more solutes inside the cells than the fresh water solution surrounding them.

On the other hand, when the flower was placed in the salt solution, it wilted because the cells were hypotonic compared to the hypertonic salt solution. There were fewer solutes in the flower cells than the salt solution outside, so water left the cells, which made the flower wilt.
