Which of the following elements are required for chlorophyll synthesis?

Options

A. Fe and Mg
B. Mo and Ca
C. Cu and Ca
D. Ca and K

Explanation

To answer the question regarding which elements are required for chlorophyll synthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chlorophyll Structure**:
- Chlorophyll is a vital pigment found in plants that is essential for photosynthesis. It contains a porphyrin ring structure.

2. **Identifying Key Elements**:
- The two key elements that are integral to the structure of chlorophyll are magnesium (Mg) and iron (Fe).

3. **Role of Magnesium**:
- Magnesium is a macronutrient and is crucial because it forms the central atom of the chlorophyll molecule. It is attached to the nitrogen atoms in the pyrrole ring of chlorophyll.

4. **Role of Iron**:
- Iron is a micronutrient that plays a significant role in the synthesis of chlorophyll. It is involved in the enzymatic processes that lead to chlorophyll formation.

5. **Conclusion**:
- Therefore, the elements required for chlorophyll synthesis are magnesium and iron.

### Final Answer:
The elements required for chlorophyll synthesis are **Magnesium (Mg)** and **Iron (Fe)**.
