AIIMS 2018 Botany Osmosis MCQ Question
Bacteria cannot survive in a highly salted pickle because
salt inhibits reproduction of bacteria.
they become plasmolysed and death occurs.
nutrients in pickle cannot support life.
enough light is not available for photosynthesis.
Correct Answer
Detailed Explanation
In a hypertonic solution, such as salted pickle, the osmotic potential is higher than that of the cell sap, causing water (H₂O) to move out of the bacterial cell through exosmosis. This loss of water leads to plasmolysis, where the cell membrane detaches from the cell wall, ultimately resulting in cell death. Other options are not relevant as they do not provide any additional information or context regarding the osmotic effects on cells in hypertonic environments. Understanding this process is crucial for grasping how osmotic pressure influences cell viability in various solutions.
