Reproduction in Bacteria
1
Conditions needed for Bacteria to reproduce
•Bacteria can rapidly reproduce
themselves in warm, dark, and moist
conditions
•Bacteria need plenty of food and the
right temperature
•Other conditions like space, oxygen
and light must also be met
2
How often do bacteria reproduce?

The time of reproduction depends on
how desirable the conditions are

Some can reproduce every 20
minutes

(one bacteria could be an ancestor to
one million bacteria in six hours)
3
Two Types of Reproduction


asexually
binary fission
sexually
conjugation.
4
Conjugation

A bridge is
formed
between two
bacteria and
genetic
information in
exchanged.
