Answer Details
The part labelled I in the diagram refers to the "lag phase". The lag phase is the first phase of bacterial growth where the bacteria are adjusting to their new environment, synthesizing new components and increasing in size, but not yet dividing. During this phase, there is little to no increase in the number of bacteria. Once the bacteria have adapted and are ready to divide, they enter the log phase, which is the phase of rapid exponential growth.
