Question

To solve the problem below, you must write a clear and convincing justification for accepting one of the possible answer choices as the best or most appropriate and for rejecting each of the other choices as less appropriate. Your reasons for rejecting choices are just as important as your reasons for choosing the best answer.

Answer 1

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.

Answer 2

@nincompoop

Answer 3

okay we can eliminate 5
The cell interior contains a variety of solutes in addition to sodium and chloride.

Answer 4

i think

Answer 5

it was actually the last one :p @nincompoop

Answer 6

Yeah I was surprised too, my friend told me and explained it to me, the first answer should be automatically eliminated since cells need sodium and chloride. And the last one is the answer because if the cell contains many solutes in addition to the sodium and chloride, then of course the cell won't show it lost water. :) @nincompoop

Answer 7

No, I have not the only experiment I can think of would be for osmosis. @nincompoop
