NEET BIOLOGY

Detailed explanation-1: -In the stationary phase, the rate of growth of the cells becomes equal to its rate of death. The rate of growth of the bacterial cells is limited by the accumulation of toxic compounds and also depletion of nutrients in the media. The cell population remains constant at this stage.

Detailed explanation-2: -…the growth rate enters a stationary phase in which the number of viable bacteria cells remains the same. During the stationary phase, the rate of bacterial cell growth is equal to the rate of bacterial cell death.

Detailed explanation-3: -The final phase of the growth curve is the death phase, which is characterized by a net loss of culturable cells. Even in the death phase there may be individual cells that are metabolizing and dividing, but more viable cells are lost than are gained so there is a net loss of viable cells.

Detailed explanation-4: -In the stationary phase, growth reaches a plateau as the number of dying cells equals the number of dividing cells. The death phase is characterized by an exponential decrease in the number of living cells.

Detailed explanation-5: -Which phase shows the reproduction rate equal to the equivalent death rate? Explanation: In the stationary phase there is a complete cessation of division and thus the reproduction rate is balanced by an equivalent death rate.
