A Ligustrum plant cell is exposed to an aqueous solution having sodium and chloride concentrations higher than the sodium and chloride concentrations of the cell interior. After thirty minutes, a biologist observes the cell under a microscope and states that the cell shows no evidence of having lost water. Which of the following best explains the observation?

A Ligustrum plant cell is exposed to an aqueous solution having sodium and chloride concentrations higher than the sodium and chloride concentrations of the cell interior. After thirty minutes, a biologist observes the cell under a microscope and states that the cell shows no evidence of having lost water. Which of the following best explains the observation?
1
The cell membrane is not permeable to either sodium or chloride.
2
The cell is surrounded by a rigid cell wall.
3
The cell protected itself by actively transporting sodium across the cell membrane into the external solution.
4
A plant cell, being different from an animal cell, cannot tolerate high concentrations of sodium and chloride and dies within 5 minutes.
5
The cell interior contains a variety of solutes in addition to sodium and chloride.
