What can protect bacteria from harsh conditions for even millions of years?
Spores are protective structures formed by certain bacteria that can withstand harsh conditions such as extreme temperatures, lack of water, and exposure to chemicals. Spores have a tough outer covering that shields the bacteria's genetic material and allows them to remain dormant until conditions improve. This resilience enables spore-forming bacteria to survive for long periods, even millions of years, in hostile environments.
With the help of endospores, or thick-walled structures that help the bacteria survive harsh conditions.

Endospores
Resistant spores are a survival mechanism for bacteria in harsh conditions. They protect the bacteria's genetic material from damage and allow them to remain dormant until conditions improve. This increases the chances of the bacteria's survival and enables them to re-establish themselves when conditions become favorable again.
The slime capsule is a protective layer that surrounds some bacteria to help them survive in harsh conditions. It can help bacteria resist desiccation, protect them from predators, and facilitate movement in certain environments.
Bacteria can respond to extreme heat by forming heat-resistant endospores, and to extreme cold by adjusting their membrane and metabolic activity. These mechanisms help protect the bacteria and allow them to survive in harsh environmental conditions.
Endospores
Some strains of bacteria like anthrax can form spores, which are highly resistant structures that protect the bacteria from harsh environmental conditions like extreme temperatures, lack of nutrients, and disinfectants. These spores can remain dormant for long periods of time until conditions become more favorable for growth and reproduction. Additionally, anthrax bacteria have developed mechanisms to repair damage to their DNA caused by environmental stressors.
Workers protested against harsh working conditions. This led to the formation of unions in order to protect the rights of the worker.
Spores are a form of reproductive structure that bacteria can produce to survive harsh environmental conditions. They can protect the bacteria from desiccation, heat, radiation, and chemical damage. Spores allow bacteria to remain dormant until conditions improve, at which point they can germinate and resume growth.
When conditions outside the bacteria get very extreme and hard to live in, the bacteria can produce endospores, these endospores store the bacteria's genetic code so the bacteria can replenish itself should it happen to die in the harsh conditions.
