What shows evidence of active transport?

Answer: Active transport is the movement of molecules

across a membrane

Movement of minerals in plant

Explanation:

In Biology, Active transport means Movement of molecules from lower concentration to Higher concentration through a membranous substance.

It is clearly shown in transportation of minerals from root hairs to root cells.

From root hairs (Lower concentration) minerals are transported to other parts of plant (Higher concentration, Active transport takes place.

It is clearly evident that in this natural process active transport of minerals takes place effectively through root hairs to various parts of plant.
