During the lag phase, which description is accurate?

During the lag phase, which description is accurate?

• A. rapid cell division
• B. cell death
• C. intense metabolic activity but no increase in cell number
• D. adaptation with growth

Answer: (C)

Lag phase is a period of adaptation where cells are highly active metabolically but not yet increasing in number. They synthesize enzymes, ribosomes, and other components needed to utilize nutrients, repair damage, and adjust transport systems, all while preparing for growth. Because the focus is on preparation rather than replication, there is little to no net increase in cell count. Once adaptation is complete, rapid cell division begins in the next phase. Rapid division would occur later, not during lag; cell death is not the defining feature of this stage; and growth without division or continued adaptation would not explain the observed spike in metabolic activity without a rise in population.
