ENDOSPORES - these are dormant cells, formed when certain genera (mainly  Clostridium  and  Bacillus)  find themselves facing adverse conditions such as lack of nutrients, drying, presence of  toxic materials, etc. Once formed, endospores can withstand extreme conditions and survive for  apparently unlimited periods of time. a. Regular forms of bacteria are known as vegetative cells. These are the ones that take in  nutrients, carry out metabolic activities, reproduce, cause disease, etc. They are susceptible to  heat, drying, lack of nutrients, etc., and most of them are relatively easy to kill. b. Sporulation or sporogenesis is the process of endospore formation. 1) Bacterial chromosome replicates. One copy plus a little cytoplasm are isolated in a small area  of the cell as the plasma membrane forms a partition called the spore septum.
