Question

Deficiency of the micronutrient zinc leads to

• A. Early senescence
• B. Underdeveloped roots
• C. Underdeveloped shoots
• D. Slow growth

Answer 1

The correct option is C

Underdeveloped shoots

Zinc is a micronutrient that is required in trace amounts by the plant. Zinc activates certain enzymes and auxin synthesis which in turn helps in the development of shoots. Thus a deficiency of zinc would result in an underdeveloped shoot system.
