What role do spores play in the life of bacteria?

Spores play an important role in the existence of bacteria, since they are primarily a way to survive bad environmental conditions for them. For example, thermophilic bacteria can withstand high temperatures. In disputes, all life processes are almost stopped. They are thickly coated, but they contain everything you need, such as DNA, to form into bacterial cells under good conditions. The best way to kill bacteria and spores is to use ultraviolet light.
