Which of the following is a characteristic of a vegetative bacterial cell?

• A. Contains a thick spore coat
• B. Highly resistant to heat and desiccation
• C. Actively metabolizing and growing
• D. In a dormant, non-reproductive state

Answer: (C)

Verified step by step guidance

1. Understand the difference between a vegetative bacterial cell and a spore. A vegetative cell is the active, metabolizing form of the bacterium, while a spore is a dormant, resistant form.
2. Recall that spores have characteristics such as a thick spore coat and high resistance to heat and desiccation, which protect them in harsh conditions.
3. Recognize that vegetative cells do not have a thick spore coat and are not highly resistant to extreme conditions; instead, they are actively growing and metabolizing.
4. Compare each option to these definitions: 'Contains a thick spore coat' and 'Highly resistant to heat and desiccation' describe spores, not vegetative cells.
5. Conclude that the characteristic 'Actively metabolizing and growing' correctly describes a vegetative bacterial cell, distinguishing it from the dormant spore state.
