What is a spore?

• A. A reproductive cell produced by viruses.
• B. Spore formation is unique to bacteria.
• C. Spore formation has no role in survival.
• D. A spore is a dormant, environmentally resistant body capable of developing into a new organism.

Answer: (D)

A spore is a dormant, environmentally resistant body capable of developing into a new organism. This captures the essential idea: spores endure harsh conditions in a protected, non-growing state and can later germinate to form a living organism when conditions improve. Spores provide a survival strategy across many organisms, not just bacteria—fungi and plants also produce spores. They are not reproductive cells produced by viruses, and spore formation does play a critical role in survival, not the opposite. So this description best fits what a spore is.
