Which statement about fungi is correct?

• A. Fungi are eukaryotes with cell walls made of chitin.
• B. Fungi are prokaryotes with peptidoglycan.
• C. Fungi are photosynthetic.
• D. Fungi are always multicellular.

Answer: (A)

Fungi are eukaryotic organisms with cell walls made of chitin. This distinguishes them from bacteria, which have peptidoglycan in their walls, and from plants, which use cellulose. Fungi do not carry out photosynthesis; they are heterotrophs that absorb nutrients from their surroundings rather than producing their own food from light. They also vary in form, with some species existing as unicellular yeasts and others as multicellular molds or mushrooms, so they are not always multicellular. The statement captures the defining traits of fungi by highlighting their eukaryotic nature and the presence of chitin in their cell walls.
