Diagram Description
Sigmoid Growth Curve
The graph shows population size on the y-axis and time on the x-axis. The curve has four phases: lag phase (initial flat section), exponential phase (steep upward slope), stationary phase (plateau), and death phase (downward slope).
- a[1]
Identify the lag phase on the sigmoid growth curve.
Aim for approximately 1 distinct marking point.
- b[1]
Identify the exponential phase on the sigmoid growth curve.
Aim for approximately 1 distinct marking point.
