The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Mycorrhizae**: Mycorrhizae are symbiotic associations between fungi and plant roots. They play a crucial role in enhancing plant growth and health. 2. **Resistance to Root-Borne Pathogens**: One of the primary benefits of mycorrhizae is that they help plants resist root-borne pathogens. The fungal network can protect the roots from harmful microorganisms. 3. **Absorption of Nutrients**: Mycorrhizae enhance the plant's ability to absorb essential nutrients, particularly phosphorus, which is often limited in the soil. This is critical for plant growth and development. 4. **Tolerance to Salinity**: Mycorrhizal associations can improve a plant's tolerance to saline conditions. This is important for plants growing in areas with high salt concentrations in the soil. 5. **Tolerance to Drought**: Mycorrhizae also help plants cope with drought conditions by improving water uptake. The extensive fungal network can access water from a larger soil volume than the plant roots alone. 6. **Overall Increase in Plant Growth and Development**: The combined effects of improved nutrient absorption, pathogen resistance, and tolerance to environmental stresses lead to an overall increase in plant growth and development. ### Conclusion: The benefits of mycorrhizae include: - A. Resistance to root-borne pathogens - B. Tolerance to salinity and absorption of phosphorus - C. Tolerance to drought - D. Overall increase in plant growth and development All options A, B, C, and D are correct.
