Which type of fungi has hyphae?

• A. Yeast
• B. Filamentous (molds)
• C. Both
• D. Neither

Answer: (B)

Hyphae are the threadlike filaments that make up the body of many fungi and form a network called a mycelium. This filamentous growth is characteristic of filamentous fungi, commonly called molds, which use hyphae to penetrate and absorb nutrients from their surroundings. Yeasts, on the other hand, are typically unicellular, existing as individual cells that reproduce by budding; they do not form hyphae in their usual form. Some yeasts can temporarily produce elongated cells or chains that resemble hyphae (pseudohyphae) under certain conditions, but the classic distinction is that hyphae are present in filamentous fungi. Therefore, the type of fungi that has hyphae is the filamentous form, the molds.
