Answer:
Endospores may be defined as the tough, dormant and the non reproductive structures formed by bacteria and they are not true spores. This is a dormant phase occurs in unfavorable environmental condition.
The endospore formulation starts when bacteria detect the unfavorable conditions. This process takes 8 hours to complete. The spore sptum forms between the cells rests. The plasma membrane pinches off and leaves the double membrane around DNA and forms forespore. The peptidoglycan forms around the forespore, then endospore formed is dehydrated and allow to mature before they are released from the mother cell.
