Iron is critical for cholorphyll formation and photosynthesis. Cholorphyll is the small "sun-panels" which the plants use to harvest energy from the sun (and which gives plants their green color). Photosynthesis is the process during which the actual sun rays are harvested. Iron is also used by enzymes to regulate transpiration in plants. Transpiration is the name we have given to the process during which plants pull water up from the ground and let it out it through small openings on the underside of the leaves. This transpiration process allows nutrients (dissolved in water) to reach all parts of the plants.
Without iron the above functions would not work. Since these functions are ESSENTIAL to plant growth, iron becomes an essential element (required for plants to grow).
Too much iron can be bad, however. It competes with zinc and copper in the soil for position (availability) to plants. Without zinc and copper plants wont grow either. Iron is only required in very small amounts which is lucky because iron is usually only available in very small amounts in the soil.
Normally, Iron deficiency (lack of iron) is typically not a problem because the small minute amounts needed are typically readily available in soil. However, in some cases, when plants are grown on soil with high levels of calcium (also called alkaline or high pH soils) iron can be tied in in the soil (e.g. is not available to the plants despite the metal is physically in soil) and then iron deficiency symptoms may show in plants. Typically this manifests itself through the bottom leaves turning yellow, stunted growth, and the plants not responding to regular fertilizer, etc.
