Q. A primary root grows from $5 \,cm$ to $19 \,cm$ in a week. Calculate the actual growth rate $(AGR)$ and relative growth rate $(RGR)$ over the period.
$AGR$ $RGR$
(a)$\,\,$ $14\,cm\,\,$ $2.8$
(b)$\,\,$ $14\,cm\,\,$ $3.8$
(c)$\,\,$ $3.8\,cm\,\,$ $14\%$
(d)$\,\,$ $24\,cm\,\,$ $2.8\%$

Plant Growth and Development

Solution:

$AGR = 1 9 - 5 = 14\, cm$
$RGR=\frac{14}{5}=2.8\,cm$
