American cockroaches generally live in moist areas, but can survive in dry areas if they have access to water. They prefer warm temperatures around 29 Â°C (84 Â°F) and do not tolerate cold temperatures.
'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.
