There are four phases in the bacterial growth curve. The phase in which the number of cells stops increasing is the exponential phase. stationary phase. log phase. death phase: lag phase. Question 4 1 pts Why are serial dilutions used with both the pour plate and spread plate methods of plating? Using serial dilutions makes it possible to identify the nonliving cells in the original sample. Using serial dilutions concentrates bacteria so that they can form colonies. It does not harm temperature-sensitive microbes. Without dilution most of the bacteria would die before the colonies formed on the agar. Without dilution the colonies would not be separated from one another and they would be difficult to count and identify.

1. There are four phases in the bacterial growth curve. The phase in which the number of cells stops
increasing is the exponential phase. stationary phase. log phase. death phase: lag phase. Question
4 1 pts Why are serial dilutions used with both the pour plate and spread plate methods of
plating? Using serial dilutions makes it possible to identify the nonliving cells in the original
sample. Using serial dilutions concentrates bacteria so that they can form colonies. It does not
harm temperature-sensitive microbes. Without dilution most of the bacteria would die before the
colonies formed on the agar. Without dilution the colonies would not be separated from one
another and they would be difficult to count and identify.
