|
Period of equilibrium in which new cell numbers are balanced by the death of cells is considered the ____
|
growth phase.
|
|
log phase.
|
|
equillibrium phase
|
|
stationary phase.
|
Explanation:
Detailed explanation-1: -Once nutrients in the medium are exhausted, bacterial culture enters a stationary phase, which is characterized by equilibrium between the numbers of dividing and dying cells and represents a plateau in the growth curve.
Detailed explanation-2: -Stationary phase is the stage when growth ceases but cells remain metabolically active. Several physical and molecular changes take place during this stage that makes them interesting to explore. The characteristic proteins synthesized in the stationary phase are indispensable as they confer viability to the bacteria.
