They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environmen â¦ t is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents).
'Once a cell is vitrified it can continue to survive right down to incredibly low temperatures. It just can't do much until it warms up.' More complex organisms are able to survive at lower temperatures because they are able to control the medium the cells sit in to some extent. 'Bacteria, unicellular algae and unicellular fungi â of which there are a huge amount in the world-are free-living because they don't rely on other organisms ,' Clarke explains.
