MCQ
Exponential growth in plants can be expressed as
- A$L_{t}=L_{o}+r t$
- B$L_{e}=L_{t} r t$
- ✓$W_{l}=W_{0} e^{rt}$
- D$W_{l}=W_{0} e^{rt}$
$W_{l}=W_{0} e^{rt}$
Where,
$W_{l}=$ Final size(weight, height, number, etc.)
$W_{0}=$ initial size of the beginning of trhe period
$r =$ Growth rate
$t =$ Time of growth
$e =$ base of natural logarithms
Here, $r$ is the relative growth rate and is also the measure of the ability of the plant to produce plant material, referred to as efficiency index. Hence, the final size of $W_{l}$ depends on the initial size $W_{0}$
