Kingdom Fungi — Select the statement that does NOT correctly describe fungi as a group.

Difficulty: Easy

Correct Answer: The fungi are eukaryotic, multicellular, ingestive heterotrophs

Explanation:


Introduction / Context:
Core traits of the fungal kingdom distinguish it from animals and plants. This question tests recognition of the correct nutritional mode and key biological features of fungi.



Given Data / Assumptions:

  • Fungi are eukaryotic and include both multicellular molds and unicellular yeasts.
  • They commonly reproduce by spores.
  • Many fungi form mutualisms (e.g., mycorrhizae) and produce secondary metabolites, including antibiotics.


Concept / Approach:
The incorrect statement labels fungi as “ingestive heterotrophs.” Animals are ingestive; fungi are absorptive (osmotrophic) heterotrophs that secrete enzymes to digest polymers externally and absorb monomers. Hence, option (a) does not apply to the kingdom Fungi.



Step-by-Step Solution:

Identify nutrition mode: fungi are absorptive, not ingestive.Confirm other traits: spores and symbioses are typical; antibiotics (e.g., penicillin) originate from fungi.Choose the statement that misclassifies fungal nutrition.


Verification / Alternative check:
Textbooks emphasize extracellular digestion and uptake across the cell wall and membrane in fungi.



Why Other Options Are Wrong:

  • (b), (c), (d) are accurate descriptions of many fungi and their ecological or biotechnological roles.


Common Pitfalls:
Assuming “heterotroph” implies ingestion; osmotrophy is a distinct strategy.



Final Answer:
The fungi are eukaryotic, multicellular, ingestive heterotrophs
