Leghaemoglobin occurs in

Options

A. Coralloid root
B. BGA
C. Around bacteriods
D. Mycorrhiza

Answer

**Step-by-Step Solution:**

1. **Understanding Leghaemoglobin**: Leghaemoglobin is a type of hemoglobin that is specifically found in certain plants. It serves as an oxygen carrier.

2. **Location of Leghaemoglobin**: It is primarily found in the root nodules of leguminous plants. These plants form symbiotic relationships with nitrogen-fixing bacteria, particularly Rhizobium.

3. **Function of Rhizobium**: The Rhizobium bacteria live within the root nodules and play a crucial role in fixing atmospheric nitrogen, converting it into a form that the plant can utilize for growth.

4. **Association with Bacteroids**: Within the root nodules, the Rhizobium bacteria differentiate into a form known as bacteroids. Leghaemoglobin is present around these bacteroids, helping to maintain an anaerobic environment which is essential for nitrogen fixation.

5. **Conclusion**: Therefore, the correct answer to the question "Leghaemoglobin occurs in" is "around bacteroids."
