Bread molds belong to which group of organisms?

• A. Bacteria
• B. Fungi
• C. Protists
• D. Plants

Answer: (B)

Bread molds are a type of fungi. They grow as filamentous networks called hyphae that bundle into a visible mat called a mycelium, and their cells have chitin in the walls. They feed by absorption—secreting enzymes to break down the bread and then taking in the nutrients—rather than by photosynthesis. They also reproduce by producing spores, which is why mold markets often appear as fuzzy, spore-bearing layers.

This distinguishes them from bacteria, which are single-celled prokaryotes with no nucleus and usually peptidoglycan in their walls; from protists, a diverse group that includes many single-celled organisms not typically seen as bread mold; and from plants, which are multicellular, photosynthetic, and have cellulose cell walls. The combination of hyphae, chitin walls, absorptive nutrition, and spore-based reproduction points to fungi.
