Plants such as cloves and beans that have nitrogen-fixing bacteria in their roots are in which of the following families?

Options

A. Orchidaceae
B. Asteraceae
C. Solanaceae
D. Leguminosae

Answer

To determine the family to which plants such as cloves and beans belong, particularly those that have nitrogen-fixing bacteria in their roots, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Plants**: The question mentions cloves and beans. We need to focus on the characteristics of these plants.

2. **Understand Nitrogen-Fixing Bacteria**: Nitrogen-fixing bacteria, such as Rhizobium, form a symbiotic relationship with the roots of certain plants, allowing them to convert atmospheric nitrogen into a form that plants can use.

3. **Determine the Plant Family**:
- Cloves belong to the family **Myrtaceae**.
- Beans, particularly common beans (Phaseolus vulgaris), belong to the family **Fabaceae** (also known as Leguminosae).

4. **Focus on Nitrogen-Fixing Capability**: The question specifically asks about plants that have nitrogen-fixing bacteria in their roots. This characteristic is primarily associated with the **Fabaceae** family, which includes legumes like beans, soybeans, and peas.

5. **Conclusion**: While cloves belong to the Myrtaceae family, the plants that have nitrogen-fixing bacteria in their roots, like beans, belong to the **Fabaceae** family.

### Final Answer:
Plants such as beans that have nitrogen-fixing bacteria in their roots belong to the **Fabaceae** family.
