Question 48
Cell and Its EnvironmentFour cells each with osmotic potential of about 3% salt solution were immersed respectively into solutions of different concentrations as follows:
I - 1% salt solution.
II - 3% salt solution.
III - 6% salt solution.
IV - 10% salt solution.
If the cells are plant cells, what would happen to the cell in solution III? It would become
- A.heamolysed.
- B.plasmolyzed.
- C.turgid.
- D.crenated.
Show the answer and explanation
Answer: B (plasmolyzed.)
Explanation
The 6% solution is more concentrated than the cell, so the cell loses water and its cytoplasm shrinks away from the wall: it is plasmolysed.
