Answer:
The correct answer will be- Endospore.
Explanation:
Bacteria under unfavourable conditions form a tough protective shell called "endospores" to ensure the survival of bacteria during environmental stress conditions.
The endospores are the tough, dormant, and non-reproductive structure produced by the bacteria belonging to the family Firmicute. The endospores provide resistance to desiccation, Â temperature, chemical disinfectants, starvation, lysozyme and ultraviolet and gamma radiation.
Thus, Endospore is the correct answer.
