What are the two major groups of fungi?

• A. They are single-celled only.
• B. They are not found in food.
• C. Yeast are multicellular.
• D. Mold and Yeast are the two major groups of fungi.

Answer: (D)

Fungi are commonly discussed by how they grow, and the two main groups you'll encounter in food microbiology are molds and yeasts. Molds form filamentous structures called hyphae and grow into visible, fuzzy or powdery colonies, so they’re typically multicellular. Yeasts, on the other hand, are mainly single-celled and reproduce by budding, appearing as small round cells. This distinction captures the primary forms you’re likely to see in foods—mold spoilage and yeast-driven fermentation. The other statements don’t fit because some fungi are multicellular (molds), fungi can be found in foods, and yeasts are not typically multicellular.
