The correct Answer is:
To determine how many of the listed plants have an association with Rhizobium, we need to identify which of these plants are known to form symbiotic relationships with Rhizobium bacteria. Rhizobium is primarily associated with legumes, which are plants in the family Fabaceae. Let's analyze each plant one by one: 1. **Sweet Pea (Lathyrus odoratus)**: This plant is a legume and can form a symbiotic relationship with Rhizobium. 2. **Lentils (Lens culinaris)**: Lentils are also legumes and have a well-known association with Rhizobium. 3. **Garden Pea (Pisum sativum)**: Garden peas are another type of legume that forms a symbiotic relationship with Rhizobium. 4. **Alfalfa (Medicago sativa)**: Alfalfa is a legume and is known to associate with Rhizobium bacteria. 5. **Alnus (Alder)**: Alnus is a genus of trees that does not associate with Rhizobium. Instead, it forms symbiotic relationships with actinobacteria such as Frankia. 6. **Frankia**: Frankia is not a plant but a genus of actinobacteria that forms symbiotic relationships with non-leguminous plants, particularly those in the family Casuarinaceae and some others. It does not have an association with Rhizobium. 7. **Soybean (Glycine max)**: Soybean is a legume and has a strong association with Rhizobium. 8. **Clover Beans (Trifolium spp.)**: Clover is also a legume and forms a symbiotic relationship with Rhizobium. Now, let's summarize the findings: - Sweet Pea: Yes (Rhizobium) - Lentils: Yes (Rhizobium) - Garden Pea: Yes (Rhizobium) - Alfalfa: Yes (Rhizobium) - Alnus: No (Frankia) - Frankia: No (not a plant) - Soybean: Yes (Rhizobium) - Clover Beans: Yes (Rhizobium) Counting the plants that have an association with Rhizobium, we find: 1. Sweet Pea 2. Lentils 3. Garden Pea 4. Alfalfa 5. Soybean 6. Clover Beans Total = 6 plants have an association with Rhizobium. **Final Answer: 6**
