What are hyphae?

• A. Bacterial filaments
• B. Plant roots
• C. Insect legs
• D. Fungal strands in soil

Answer: (D)

Hyphae are thread-like filaments that compose the body of fungi. In soil, these fungal strands spread through decaying organic matter and the mineral soil, forming an extensive network called a mycelium. This network releases enzymes that break down tough materials like cellulose and lignin, freeing nutrients for plants and other organisms. That decomposition and nutrient release are central to soil health and nutrient cycling in rangeland soils. Hyphae are distinct from bacterial filaments, and plant roots or insect legs are not hyphae. In addition to decomposition, fungal hyphae can help bind soil particles to improve structure, and many form mycorrhizal partnerships with plant roots to boost water and nutrient uptake. So, hyphae are fungal strands in soil.
