Which term describes a dormant, resistant form that bacteria form to survive unfavorable conditions?

• A. Endospore
• B. Eukaryote
• C. Prokaryote
• D. Nitrogen fixation

Answer: (A)

Bacteria form endospores to survive unfavorable conditions. An endospore is a dormant, highly resistant structure that protects the cell’s DNA and essential machinery when nutrients are scarce or stress is extreme. It features a tough coat and a dehydrated, metabolically inactive core, allowing it to resist heat, drying, chemicals, and radiation. When conditions improve, the endospore can germinate back into a normal, active bacterium. Other terms describe different ideas: a eukaryote is a cell with a nucleus and organelles, not a dormant survival form; a prokaryote is a simple cell type without a nucleus, not a state of dormancy; nitrogen fixation is a metabolic process that converts atmospheric nitrogen into ammonia, not a survival structure.
