What is translocation? Explain.

(N/A) $\Rightarrow$ In a flowering plant,the substances that need to be transported include water,mineral nutrients,organic nutrients,and plant growth regulators.
$\Rightarrow$ Over small distances,substances move by diffusion and cytoplasmic streaming,supplemented by active transport.
$\Rightarrow$ Transport over longer distances proceeds through the vascular system,which consists of the xylem and the phloem.
$\Rightarrow$ This process of long-distance transport of substances through the vascular system is called translocation.
