Which morphological description matches Zygomycetes?

Which morphological description matches Zygomycetes?

• A. Septate hyphae with sporangiospores
• B. Non-septate hyphae with sporangia
• C. Septate hyphae with conidiospores
• D. Septate hyphae with zygospores

Answer: (A)

Zygomycetes are characterized by non-septate (coenocytic) hyphae and the production of spores in sporangia (sporangiospores) during asexual reproduction. They also form zygospores during sexual reproduction when two compatible hyphae fuse. Because the defining growth form is the coenocytic hyphae and the presence of sporangia with sporangiospores, the description that emphasizes sporangia-bearing hyphae best matches this group. Descriptions with septate hyphae point to other fungi, and conidiospores are more typical of many Ascomycota or related fungi, not Zygomycetes.
