Nonfilamentous fungi are generally what in cellular organization?

• A. Unicellular
• B. Multicellular
• C. Aerial-only
• D. Lacks nuclei

Answer: (A)

Nonfilamentous fungi are typically unicellular organisms. The term nonfilamentous highlights that they lack the long hyphal networks that define filamentous molds; instead, these fungi mainly exist as single cells, often reproducing by budding or fission, as seen in yeasts. Fungi are eukaryotes, so they possess nuclei, which makes the option lacking nuclei incorrect. Multicellular would describe organisms that form filaments or tissues, not the single-cell form that characterizes nonfilamentous fungi. Aerial-only isn’t a standard descriptor of their cellular organization. So the best fit is unicellular.
