As we know certain species of bacteria produce spores, these all are the characterstics of a spore except:
Correct answer: D. Spores can never germinate into vegetative cells
- A. Spores can be located outside the vegetative cells
- B. Spores exhibit resistance to harsh environmental conditions
- C. Spores can form within vegetative cells
- D. Spores can never germinate into vegetative cells
Explanation
Bacterial spores, especially endospores, are highly resistant structures formed by certain bacteria such as those in the genera Bacillus and Clostridium. These spores can survive in harsh conditions by entering a dormant state. When conditions improve, they can germinate back into vegetative cells. The statement that spores 'can never germinate into vegetative cells' is incorrect, making it the correct choice in this context. The other options describe accurate characteristics of bacterial spores, thereby making them incorrect choices.
