For chlorophyll formation in plants, elements needed are

Options

A. Sodium and copper
B. Calcium and potassium
C. Iron and magnesium
D. Iron and calcium

Answer

To answer the question regarding the elements needed for chlorophyll formation in plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chlorophyll**:
- Chlorophyll is a green pigment essential for photosynthesis in plants. It captures light energy, which is then converted into chemical energy.

2. **Identifying Key Elements**:
- Chlorophyll is primarily composed of a cyclic tetrapyrrole structure, which includes a central metal ion. The two key elements involved in chlorophyll formation are magnesium and iron.

3. **Role of Magnesium**:
- Magnesium is a crucial component of the chlorophyll molecule. It is coordinated to the four pyrrole rings in the cyclic tetrapyrrole head of chlorophyll. Without magnesium, chlorophyll cannot be formed.

4. **Role of Iron**:
- Iron is classified as a micronutrient and is essential for the synthesis of chlorophyll. It plays a vital role in various biochemical processes within the plant, including the formation of chlorophyll.

5. **Conclusion**:
- Therefore, the elements needed for chlorophyll formation in plants are **Iron and Magnesium**.

### Final Answer:
The elements needed for chlorophyll formation in plants are **Iron and Magnesium**.
