🔬 Classification of Rhizopus

  • Division : Eumycota

  • Class : Zygomycetes

  • Order : Mucorales

  • Family : Mucoraceae

  • Genus : Rhizopus

✨ Characters of Rhizopus (Specimen)

  1. The plant body of Rhizopus is called mycelium, usually growing as a saprophyte.

  2. Mycelium consists of three kinds of hyphae:

    • Stolons

    • Rhizoids

    • Sporangiophores

  3. Stolons grow horizontally on the substratum.

  4. Rhizoids penetrate into the substratum and absorb nutrients.

  5. Hyphal wall is made of fungal chitin.

  6. Asexual reproduction occurs through sporangiospores formed inside sporangia.

  7. Sporangiophores are aerial, erect, unbranched reproductive hyphae that arise opposite to rhizoids.

  8. Each sporangiophore bears a single spherical sporangium at its tip.

  9. Inside the sporangium, a dome-shaped columella is present.

  10. Each sporangium produces a large number of spherical, non-motile, multinucleate spores.

👉 Based on these features, the specimen is identified as Vegetative Mycelium of Rhizopus.

  • Sporangiospores

  • Sporangiophore

  • Rhizoids

✅ Thus, Rhizopus is an important fungus showing clear mycelial differentiation and asexual reproduction through sporangiospores.
