Growth Kinetics
Whole Organs: S-Shaped Growth Curve
- Phases of a sigmoidal growth curve
- Logarithmic Phase:
- Size (V) increases exponentially with time (t)
- Growth rate (dV/dt)
- Rate is slow at first
- Rate continually increase
- Rate is proportional to size of the organism
- Larger the organism, the faster it grows
- Linear Phase
- Increase in size continues at a constant rate
- Senescence Phase
- Decreasing growth rate as plant reaches maturing and begins to senesce.
