Vedclass · Answer

(D) Root elongation typically follows an arithmetic growth pattern,where the growth rate is constant over time. In arithmetic growth,the mathematical expression is $L_t = L_0 + rt$,where $L_t$ is the length at time $t$,$L_0$ is the initial length,and $r$ is the growth rate. Statement $a$ is true because the rate of elongation is constant. Statement $c$ is true because root elongation is a classic example of arithmetic growth. Statement $b$ is false because the equation $W_t = W_0 e^{rt}$ represents geometric (exponential) growth,which is characteristic of cell division,not the linear elongation of roots. Therefore,both $a$ and $c$ are true.
