Difference Between Mucor and Rhizopus | Mucor vs Rhizopus

Mucor reproduces through sexual and asexual reproduction. Asexual reproduction in Mucor takes place through fragmentation and through sporangiophore formation. The sporangiophore of Mucor is branched. Upon maturity, the sporangiophore develops into a sporangium and releases asexual spores. These asexual spores then develop into new functional Mucor mycelia.

Sexual reproduction in Mucor takes place through the mating of the two types of organisms. Sexual reproduction in Mucor takes place under harsh unfavorable conditions. Moreover, the gametangia of Mucor reproduce via conjugation.

What is Rhizopus?

Rhizopus belongs to the Phylum Zygomycota of kingdom Fungi. They are soil organisms but are also found in surfaces of rotten food. They have a distinct body structure composed of rhizoids and stolons. These fungi anchor to the soil by their rhizoids. Moreover, rhizoids help to absorb nutrients from the soil. Their colonies are black in colour.

Similar to Mucor, Rhizopus also show both asexual and sexual reproduction patterns. Vegetative reproduction takes place via fragmentation and the production of asexual spores inside the unbranched sporangiophores. Meanwhile, sexual reproduction takes place through gamentagial conjugation in Rhizopus. Moreover, Rhizopus is an industrially important fungus.

What are the Similarities Between Mucor and Rhizopus?

  • Mucor and Rhizopus are two fungi that belong to kingdom Fungi and phylum Zygomycota.
  • Both organisms show heterotrophic nutrition.
  • Also, they are saprotrophs.
  • Both carry out extracellular digestion.
  • Their hyphae are branched.
  • Moreover, the cell wall of both fungi is composed of chitin.
  • Besides, both fungal species are found in soil and in rotten food surfaces.
  • They reproduce via both asexual and sexual methods.
  • Vegetative reproduction takes place via fragmentation in both fungi.
  • Furthermore, sporangiophore contains asexual spores that are important in asexual reproduction of both organisms.
  • Sexual reproduction takes place through gametangial conjugation in both Mucor and Rhizopus.

What is the Difference Between Mucor and Rhizopus?

Mucor and Rhizopus are two types of filamentous fungi which are molds. They look alike. But they can be distinguished by the presence or absence of rhizoids and stolons. Mucor does not have rhizoids and stolons while Rhizopus has rhizoids and stolons. So, we can consider this as the key difference between Mucor and Rhizopus. Furthermore, a significant morphological difference between Mucor and Rhizopus is that the Mucor looks like white cotton candy colonies whereas Rhizopus appears as black color cotton candy colonies.

Moreover, though both fungi produce sporangiophores, Mucor has branched sporangiophores while Rhizopus has unbranched sporangiophore. Therefore, this is also a difference between Mucor and Rhizopus.
