Which of the following is must for chlorophyll synthesis

Options

A. Fe
B. Mg
C. K
D. Mn

Answer

**Step-by-Step Solution:**

1. **Understanding Chlorophyll**: Chlorophyll is the green pigment found in plants that is essential for photosynthesis, allowing plants to convert sunlight into energy.

2. **Structure of Chlorophyll**: The chlorophyll molecule has a specific structure that includes a tetrapyrrole head and a tail region. The tetrapyrrole head is crucial for its function.

3. **Role of Magnesium**: Within the tetrapyrrole head of chlorophyll, there is a magnesium ion (Mg²⁺) at the center. This magnesium is coordinated to the four pyrrole rings, making it essential for the chlorophyll's structure and function.

4. **Role of Other Elements**: While iron (Fe) is also involved in the synthesis of chlorophyll and performs vital functions, magnesium is the primary element required for the synthesis of chlorophyll.

5. **Conclusion**: Based on the structure and function of chlorophyll, magnesium is the must-have element for chlorophyll synthesis.

**Final Answer**: Magnesium is essential for chlorophyll synthesis.
