Question

Which one of the following is incorrect about fungi?

• A. They are heterotrophic.
• B. They are both unicellular and multicellular.
• C. They are eukaryotic.
• D. All fungi posses a purely cellulosic cell wall.

Answer 1

The correct option is D All fungi posses a purely cellulosic cell wall.

• Fungi are saprotrophs or parasites (heterotrophic i.e., organisms that cannot synthesize organic compounds and depend on available ones).
• Fungi can derive their nutrition from live or dead organisms.
• Yeast is a unicellular fungus, while all other fungi are multicellular.
• The presence of a chitinous cell wall is a characteristic feature of fungi whereas a cellulosic cell wall is found in plants.

Therefore, the correct answer is option D.
