What is the role of spores in the life of bacteria?

The sporulation process is a mechanism that helps bacterial cells survive in adverse environmental conditions. Not all bacteria form spores. There are 15 genera of bacteria capable of forming spores. There are 2 types of spore formation in bacteria: 1) spores that form inside the “mother” cell, 2) spores budding from one of the poles of the “mother” cell. In general, the main importance of spores for bacteria is to provide resistance to adverse conditions.
