Question

We can keep food for longer duration in cold storage than in ordinary cupboard because

• A. Insects cannot cause infection
• B. Bacterial multiplication is completely prevented
• C. Bacterial multiplication is greatly reduced
• D. Low temperature causes plasmolysis

Answer 1

The correct option is C Bacterial multiplication is greatly reduced

We can keep food for longer duration in cold storage than in ordinary cupboard because bacterial multiplication is greatly reduced. At room temperature, bacteria grow rapidly. When food is stored at cold temperature, bacteria enters a dormant stage. Also, water content of the food freezes in cold storage. This prevents bacteria from multiplying and food spoiling.

Thus, the correct answer is 'Bacterial multiplication is greatly reduced.'
