Question

Given below is a graph drawn on the parameters of growth versus time A, B, C respectively represent which of the following sequence?

• A. Exponential phase, log phase and steady state phase.
• B. Steady state phase, log phase and lag phase.
• C. Slow growing phase, lag phase and steady state phase.
• D. Lag phase, steady state phase and logarithmic phase.
• E. Lag phase, log phase and steady state phase.

Answer 1

The correct option is B Steady state phase, log phase and lag phase.

There are different phases in the stages of growth. It follows a sigmoid curve. The initial growth phase, during which cell number remains relatively constant prior to rapid growth.The phase next to it is log phase which is otherwise called as exponential phase, which has a lot of growth involved in it. The final stage is steady state phase where the growth stops.
