Which one of the following pairs is correctly matched?a)Rhizobium- Par...
The correct match is:
- B: Mycorrhiza - Mineral uptake from soil
Explanation:
- Mycorrhiza is a symbiotic association between fungi and plant roots.
- Fungi help plants absorb essential nutrients like phosphorus and nitrogen from the soil.
- In return, the fungi receive sugars and other organic compounds from the plant.
- This relationship enhances the plant's ability to uptake minerals, aiding in its growth and overall health.

Understanding Mycorrhiza
Mycorrhiza is a symbiotic association between fungi and the roots of plants. This relationship is crucial for enhancing mineral uptake, particularly phosphorus, from the soil.
Key Functions of Mycorrhiza:
- Enhanced Nutrient Absorption:
Mycorrhizal fungi extend the root system of plants, allowing them to access more nutrients and water than roots alone could.
- Improved Soil Structure:
The fungal hyphae help bind soil particles together, improving soil structure and aeration.
- Disease Resistance:
Mycorrhizae can also help protect plants from soil-borne pathogens, enhancing overall plant health.
- Increased Drought Tolerance:
The extended network of mycorrhizal fungi improves the plant's ability to absorb water, aiding in drought conditions.
Other Options Explained:
- Rhizobium:
Misleadingly labeled as a parasite, Rhizobium is actually a beneficial bacterium that forms nodules on the roots of leguminous plants, fixing atmospheric nitrogen.
- Yeast:
Yeasts are primarily used in fermentation processes, such as baking and brewing, rather than in biogas production.
- Myxomycetes:
These are slime molds and are not responsible for causing ringworm, which is a fungal infection caused by dermatophytes.
Conclusion:
Thus, option 'B' is correctly matched as Mycorrhiza plays a vital role in mineral uptake from the soil, fostering better growth and resilience in plants. Understanding these relationships is essential for enhancing agricultural productivity and environmental health.
