Solution
The correct option is A True Answer: True.
The conduction of absorbed minerals in a plant occurs by xylem against the concentration gradient.
Unlike water, all minerals cannot be passively absorbed by the roots.
Therefore, most minerals must enter the root by active absorption.
After the ions have reached xylem through active or passive uptake, or a combination of the two, these ions are transported to different parts of the plant.
