The correct answer is Hyphae.

Key Points

  • Hyphae are the thread-like structures that make up the body of fungi including Rhizopus.
  • They are responsible for the growth and nutrient absorption of the fungus, not directly involved in reproduction.
  • While they are essential for the overall lifecycle of the fungus, they do not produce spores.
  • Reproductive structures in Rhizopus include spores, sporangium, and sporangiophores.

 Additional Information

  • Spores
    • Spores are reproductive cells capable of developing into a new individual without fusion with another cell.
    • They are produced by the sporangium and are a key element in the reproductive cycle of fungi like Rhizopus.
  • Sporangium
    • The sporangium is a structure within which spores are produced and stored until they are released.
    • It is typically found at the tip of a sporangiophore in fungi like Rhizopus.
  • Sporangiophores
    • Sporangiophores are specialized hyphal structures that bear sporangia.
    • They elevate the sporangium for effective spore dispersal.
