Which group includes multicellular molds and single-celled yeasts?

• A. Bacteria
• B. Archaea
• C. Fungi
• D. Algae

Answer: (C)

Fungi are the group that includes both multicellular molds and unicellular yeasts. Molds grow as networks of threadlike structures called hyphae that form a visible filmy mass, while yeasts are single-celled organisms that reproduce by budding. Fungi have cell walls made of chitin and are heterotrophic, absorbing nutrients from their surroundings. They are eukaryotes, distinct from bacteria and archaea, which are prokaryotes lacking a nucleus, and from algae, which are typically photosynthetic and can be quite different in lifestyle. This combination of mold-forming and yeast-forming members places them squarely in the fungal group.
