|
Time it takes a population to double
|
|
|
What happens in the lag phase?
|
Adjusting to environment, increase of cell size, cellular metabolism increases
|
|

|
What happens in the log phase?
|
Rapid rate of binary fission until maximum number of cells has been reached
|
|

What occurs in the stationary phase?
|
Number of replication vs death is at equal amount.
|
|
|
Is there an increase in bacterial growth during the stationary phase?
|
No increase
|
|
|
Why is there no increase in numbers during the stationary phase?

|
|
Why is there no replication during the decline or death phase?
|
Because of depletion of nutrients and buildup of metabolic wastes
|
|
