Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why do bacteria enters the stationary phase?
A
Because of the limitation of essential nutrients and accumulation of toxic by-products.
B
Because they get tired.
C
Because of depletion of nutrients.
D
None of the above
Explanation: 

Detailed explanation-1: -The log phase continues until nutrients are depleted or toxic products accumulate, at which time the cell growth rate slows, and some cells may begin to die.

Detailed explanation-2: -Stationary Phase: Eventually, the population growth experienced in the log phase begins to decline as the available nutrients become depleted and waste products start to accumulate. Bacterial cell growth reaches a plateau, or stationary phase, where the number of dividing cells equal the number of dying cells.

Detailed explanation-3: -In the gram-negative bacteria so far studied, nutrient starvation results in reductive division, giving rise to cells with an altered morphology and an increased long-term survival potential (10, 19, 21).
