Mycorrhizal hyphae prove useful to the plant by

Options

A. Protecting them from microbial infection
B. Providing them additional support
C. Enhancing the water absorption and uptake of minerals
D. Storing the minerals

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhizal Hyphae**: Mycorrhizal hyphae are fungal filaments that form a symbiotic relationship with plant roots. This relationship benefits both the fungi and the plants.

2. **Symbiotic Relationship**: In this relationship, both partners gain advantages. The fungi receive carbohydrates from the plant, while the plant benefits from the fungi’s ability to absorb nutrients and water.

3. **Nutrient Supply**: One of the primary benefits of mycorrhizal hyphae to plants is the supply of essential nutrients, particularly phosphorus and nitrogen. These nutrients are crucial for plant growth and development.

4. **Increased Surface Area**: Mycorrhizal hyphae increase the surface area of the plant’s root system. This expanded surface area allows for greater absorption of water and minerals from the soil.

5. **Water and Mineral Uptake**: With the enhanced surface area, mycorrhizal hyphae significantly improve the plant's ability to absorb water and essential minerals, which are vital for various physiological processes in the plant.

6. **Conclusion**: Therefore, mycorrhizal hyphae prove useful to the plant primarily by enhancing water absorption and the uptake of minerals.

**Final Answer**: Mycorrhizal hyphae prove useful to the plant by enhancing water absorption and the uptake of minerals.
