sporulation

Sporulation is a biological process where organisms form spores, which are dormant, resting cells. This is not a mandatory part of a cell's life cycle but rather an interruption to enhance survival under harsh conditions, such as nutritional deprivation.1

In bacteria, this process can lead to the formation of endospores, cysts, or heterocysts, depending on the bacterial group. Endospores, found in genera like Bacillus and Clostridium, are highly resistant to heat, dehydration, freezing, chemicals, and radiation due to their low water content and protective layers. Cysts, produced by bacteria like Azotobacter, are also resistant to harsh conditions but to a lesser extent than endospores.1

Fungi also produce vast quantities of spores as a primary reproductive unit, formed through asexual or sexual reproduction. These spores, when they land in a suitable environment, germinate and grow into new individuals. Sporulation is essentially the formation of these spores.2345
