MCQ
What does a plant cell show if placed in sea water:
✓
Plasmolysis
B
Reverse osmosis
C
Deplasmolysis
D
Diffusion
✓
Answer
Correct option: A.
Plasmolysis
The seawater is hypertonic to cell sap because of the higher concentration of dissolved solutes.
Thus, water will move out of the cells towards the surrounding solution i.e. from high water potential to low water potential.
This leads to the shrinking of protoplasm away from the cell wall of a plant or bacterium. This is known as plasmolysis.
Hence, if we place a plant cell in seawater it will undergo plasmolysis.
