A bacterium undergoing sporulation will first replicate its DNA ,The replicated DNA as well as a small amount of cytoplasm is segregated at one end of the cell,The plasmid membrane of the bacterium then grows inwards to eventually separate replicated DNA and the surrounding cytoplasm from the rest of the cells. water diffuses from this small segregated portion into the surrounding cell and then new endospore develops a thick protein coat once the formation of the endospore is complete the original cell wall dissolves and parent cell dies. the endospore is released from the dead parent cell
