Solution(By Examveda Team)

Plants use zinc as Zn²⁺.
The Zn²⁺ cation is the predominate form taken up by plants. Function: Zinc is a component of many organic complexes and DNA proteins. It is also an important enzyme for protein synthesis.
It is used in the formation of chlorophyll and some carbohydrates and is used in the conversion of starches to sugars. Zinc is essential in the formation of auxins, which help with growth regulation and stem elongation.
