C) lag growth phase.
D) death growth phase.

Question

Quizplus · Accepted Answer

By controlling the nutrient concentration in a chemostat, cells can be maintained at the exponential growth phase, where the growth rate is constant and population size increases exponentially. This is achieved by adding nutrients in a continuous manner at a rate that is optimal for the growth of the cells. The stationary phase is reached when the nutrients become limiting, and the growth rate slows down, leading to a stable population size. The lag phase is the period when the cells are adapting to new conditions and have not yet started to divide, while the death phase occurs when cells start to die due to nutrient depletion, accumulation of waste products, or other environmental stresses.
