simple cell division
What is binary fission ?
when
one
bacterial cell splits into
two
bacterial cell
When can binary fission be carried out ?
once every
20
minutes as long as they have
enough
nutrients
and the
temperature
is
suitable
How do you calculate the number of bateria presents ?
number of bacteria =
2
n
n
=
numbers
of
rounds
of
division
Example on how to work out how many bacteria there are
3 hours =
180
minutes
180
/
20
=
9
rounds of division
number of bacterium =
2^9
=
512
standard
form
= 5.12 x 10^2
