Question

Bacteria cannot survive in a highly salted pickle because

• A. Salts inhibit reproduction
• B. Bacteria do not get enough light for photosynthesis
• C. They become plasmolysed and consequently die
• D. The pickle does not contain nutrients necessary for bacteria to live

Answer 1

The correct option is C They become plasmolysed and consequently die

Bacteria cannot survive in a highly salted pickle. When bacteria are added to hypertonic medium like the salted pickle, water moves from hypotonic media, bacterial cell to hypertonic media, pickle. Due to plasmolysis, the bacterial cell will shrink and consequently die.

Thus, the correct answer is 'They become plasmolysed and consequently die.'
