Passage I
Bacteria reproduce by a process in which a single cell divides into two cells. The average time required for bacteria to divide and their population to double is called the generation time. Table 1 presents the generation time for a variety of bacteria at a given temperature.
Bacterial population growth occurs in a series of distinct steps referred to as a bacterial growth curve. It consists of 4 phases, which reflect changes in the cells' environment and metabolism over time. See Figure 1.
3. Based on the data presented in Table 1, which of the following bacteria growing in glucose broth took the longest time to double its population?
