Septum (cell biology)

A septum in cell biology is the new cell wall that forms between two daughter cells as a result of cell division. Cell division is an extremely complex process that contains four different subprocesses. These processes included the growth of a cell, DNA replication, the process of allocating replicated chromosomes to daughter cells, and septum formation. Ultimately, the septum is the crucial ending to mitosis, meiosis, and the division of bacterial cells. The formation of the septum (a new cell wall) allows the two daughter cells to be separate from one another and perform their respective functions independently.
