Solution
Plants need a tiny amount of iron in order to be healthy.
Plant roots absorb Fe most readily from the soilsolution as (ferrous) Fe2+, however, but in some cases also as (ferric) Fe3+ ions.
The chemical nature of Fe allows it to have an important role in oxidation and reduction reactions, photosynthesis, respiration, and enzyme reactions.
