Electrolysis Practice Exam

Which of the following statements is true regarding spores?

1. They thrive in aerobic conditions

2. They are easily destroyed by heat

3. They allow bacteria to survive adverse conditions

4. They are a form of active bacteria

The correct answer is: They allow bacteria to survive adverse conditions

Spores, specifically bacterial spores, play a crucial role in the survival of bacteria under harsh environmental conditions. When faced with unfavorable conditions such as extreme heat, desiccation, or nutrient scarcity, certain bacteria can form spores. These spores are highly resistant structures that can withstand extreme temperatures, radiation, and chemical exposure, allowing the bacteria to survive until conditions become favorable again. In contrast to actively growing bacteria, spores are in a dormant stage, which helps them endure unfavorable environments. This ability to form spores is vital for the survival and propagation of bacterial species, making the statement about spores allowing bacteria to survive adverse conditions accurate.
