Which micronutrient is required in larger amount in comparison to any other micronutrients?

Options

A. Fe
B. Mn
C. Ni
D. B

Answer

**Step-by-Step Solution:**

1. **Understanding Micronutrients**: Micronutrients are essential elements that plants require in small amounts for their growth and development. They include elements such as iron, manganese, nickel, boron, copper, molybdenum, zinc, and chlorine.

2. **Categories of Nutrients**: Nutrients are categorized into macronutrients (needed in larger amounts) and micronutrients (needed in smaller amounts). While macronutrients include nitrogen, phosphorus, and potassium, micronutrients are required in trace amounts.

3. **Identifying the Micronutrients**: Among the listed micronutrients (iron, manganese, nickel, and boron), we need to determine which one is required in the largest amount.

4. **Comparing Micronutrients**:
- Iron is known to be a crucial micronutrient for plants.
- It plays a significant role in various physiological processes, including chlorophyll formation, enzyme activation (like catalase), and functioning as a component of electron transport proteins.

5. **Conclusion**: Based on the comparison, iron is the micronutrient that is required in larger amounts compared to other micronutrients like manganese, nickel, and boron.

6. **Final Answer**: The micronutrient required in larger amounts in comparison to any other micronutrient is **iron**.
