Question

Difficulty: EasyTaxonomy and Classification

Match each biological kingdom to its primary cellular and nutritional characteristics.

  • PlantaeMulticellular autotrophs with cell walls composed of cellulose
  • FungiAbsorptive heterotrophs with cell walls composed of chitin
  • AnimaliaMulticellular ingestive heterotrophs that lack cell walls
  • ProtistaMostly unicellular eukaryotes that do not fit into other specialized kingdoms

Answer

Plantae matches multicellular autotrophs with cellulose walls; Fungi matches absorptive heterotrophs with chitin walls; Animalia matches multicellular heterotrophs lacking cell walls; Protista matches mostly unicellular eukaryotes.
Each kingdom in Domain Eukarya is distinguished by specific cellular structures and modes of nutrition: plants are autotrophic with cellulose walls, fungi absorb nutrients through chitin walls, animals ingest nutrients and lack cell walls, and protists represent simple, predominantly single-celled eukaryotes.

Step-by-Step Solution

1
Identify the defining features of Kingdom Plantae
Matched with multicellular autotrophs containing cellulose cell walls
Plants perform photosynthesis using chlorophyll and have structural cell walls made of cellulose.
2
Identify the defining features of Kingdom Fungi
Matched with absorptive heterotrophs containing chitin cell walls
Fungi cannot perform photosynthesis and rely on external absorption of nutrients through chitin-reinforced walls.
3
Identify the defining features of Kingdom Animalia
Matched with multicellular ingestive heterotrophs without cell walls
Animals ingest food internally and possess flexible cells without rigid walls.
4
Identify the defining features of Kingdom Protista
Matched with mostly unicellular eukaryotes
Protists are primarily microscopic, single-celled eukaryotes that lack the tissue specialization of plants, animals, or fungi.

Key Concept

Major diagnostic characteristics separating eukaryotic kingdoms based on cell structure, nutritional mode, and cell wall composition.
