Bacterial Reproduction
 How do bacteria reproduce?
-Bacteria reproduce mostly asexually. That means that
new cells are formed during single cell division. Some
bacteria can only reproduce sexually, with a male and
female bacteria.
Bacterial Reproduction
 The events of growth and division that are apparent from measurement
of the numbers of living bacteria are the manifestation of a number of
molecular events. At the level of the individual bacteria, the process of
growth and replication is known as binary division. Binary division
occurs in stages. First, the parent bacterium grows and becomes larger.
Next, the genetic material inside the bacterium uncoils from the
normal helical configuration and replicates.
 The two copies of the genetic material migrate to either end of the
bacterium. Then a cross-wall known as a septum is initiated almost
precisely at the middle of bacterium. The septum grows inward as a
ring from the inner surface of the membrane. When the septum is
complete, an inner wall has been formed, which divides the parent
bacterium into two so-called daughter bacteria. This whole process
represents the generation line.
