Bacterial Spores: Structure and Spore-Forming Bacteria
Bacterial cell undergoes spore formation in nutritionally deprived conditions, and this process is called sporulation. Spore develops from a portion of protoplasm (forespore) near one end of the cell.

Bacterial spore is a resistant structure to unfavorable environmental conditions. Each cell produces only one spore and each spore, in turn, germinate into one vegetative cell. The spore is just a part of the life cycle of spore forming bacteria under unfavorable conditions.
