Which statement is true about true hyphae?

• A. They have regular constrictions along their length
• B. They are always septate
• C. They are filamentous and lack points of constriction
• D. They reproduce by budding

Answer: (C)

True hyphae are the filamentous, thread-like structures that make up the fungal mycelium. They grow by tip extension and form long, continuous tubes. They are not produced by budding, and they do not show constrictions at the junctions between cells—if septa are present, they are cross walls with pores rather than constrictions. Some true hyphae are septate, others are non-septate (coenocytic), so being always septate isn’t accurate. This combination—filamentous structure and absence of constrictions formed by budding—best matches the description of true hyphae.
