Threadlike structure in fungi is called?

This question delves into the fundamental structural components of fungi. Fungi possess a distinct cellular organization that differentiates them from plants and animals, crucial for their unique modes of nutrition and reproduction.

• Hypha (C) is the correct answer. A hypha (plural: hyphae) is the basic structural unit of most fungi. These are long, branching, thread-like filaments that make up the body of a fungus. They are responsible for nutrient absorption and growth.
• Spore (A) is a reproductive cell, typically microscopic, that fungi use for dispersal and propagation, not the thread-like body structure.
• Mycelium (B) refers to the entire mass or network of hyphae that constitutes the vegetative part of a fungus. While composed of hyphae, 'mycelium' describes the collective structure, not an individual thread.
