Vedclass · Answer

(D) Absolute growth is the total growth of a system per unit time. Here,the leaf grows from $5 \, cm^2$ to $10 \, cm^2$,so the absolute growth is $10 \, cm^2 - 5 \, cm^2 = 5 \, cm^2$.Relative growth is the growth per unit time expressed on a common basis (initial size). It is calculated as: $	ext{Relative growth} = \frac{	ext{Absolute growth}}{	ext{Initial size}} 	imes 100$.Relative growth = $\frac{5 \, cm^2}{5 \, cm^2} 	imes 100 = 100 \%$.Therefore,the absolute growth is $5 \, cm^2$ and the relative growth is $100 \%$.
