~~9. what are the haploid reproductive structures of fungi called? (1 point)
Katarina [22]
The correct answer is the spores. Fungi reproduce asexually by budding, fragmentation, or spore production. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte.
