What is true about Arithmetic and Geometric growth curves?
Options
- ABoth are exponential.
- BBoth are linear.
- CArithmetic growth curve is linear while Geometric growth curve is exponential.
- DArithmetic growth curve is exponential while Geometric growth curve is linear.
Correct answer
C. Arithmetic growth curve is linear while Geometric growth curve is exponential.
Step-by-step solution
In arithmetic growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures. This results in a constant growth rate, and plotting growth against time yields a linear curve. The mathematical expression is L_t = L₀ + rt . In geometric growth, both progeny cells retain the ability to divide and continue to do so. The growth is initially slow (lag phase) and then increases rapidly at an exponential rate (log or exponential phase). Plotting this growth aga
