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

Options

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

Answer

To determine which micronutrient is required in larger amounts compared to others, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Nutrients**:
- Plants require 17 essential elements for growth, which are classified into two categories: macronutrients and micronutrients.
- Macronutrients are needed in larger quantities, while micronutrients are required in smaller amounts.

2. **Identify the Macronutrients and Micronutrients**:
- Macronutrients include Hydrogen, Carbon, Oxygen, Nitrogen, Phosphorus, Potassium, Sulfur, Magnesium, and Calcium.
- Micronutrients include Iron, Molybdenum, Boron, Chlorine, Copper, Zinc, Nickel, and Manganese.

3. **Focus on the Given Options**:
- The options provided are Iron, Manganese, Nickel, and Coral.
- Among these, Iron is the only micronutrient listed.

4. **Evaluate the Requirement of Each Micronutrient**:
- Iron is crucial for various metabolic processes in plants, such as:
- DNA synthesis
- Respiration
- Photosynthesis
- Maintenance of chloroplasts
- Synthesis of chlorophyll

5. **Compare Iron with Other Micronutrients**:
- While all micronutrients are essential, Iron is required in larger amounts compared to other micronutrients like Manganese and Nickel.

6. **Conclusion**:
- Based on the understanding of nutrient requirements and the specific functions of Iron in plants, we conclude that Iron is the micronutrient required in larger amounts compared to any other micronutrient.

### Final Answer:
Iron is the micronutrient required in larger amounts in comparison to any other micronutrients.
