Questions with solutions
Q1 — Kingdom Animalia · easy · theory
Members of Kingdom Animalia are:
A. Prokaryotic
B. Autotrophic with cell walls
C. Unicellular only
D. Multicellular, heterotrophic eukaryotes without cell walls ✓ Correct
Solution: Animals are multicellular, heterotrophic (holozoic) eukaryotes lacking cell walls and chlorophyll.
Q2 — Kingdom Animalia · easy · theory
The mode of nutrition in most animals is:
A. Photosynthetic
B. Holozoic (ingestion of food) ✓ Correct
C. Absorptive (like fungi)
D. Chemosynthetic
Solution: Animals typically ingest food and digest it internally — holozoic nutrition.
Q3 — Kingdom Animalia · easy · theory
The stored food (reserve carbohydrate) in animal cells is:
A. Cellulose
B. Glycogen ✓ Correct
C. Starch
D. Inulin
Solution: Animals store energy as glycogen, as do fungi.
Q4 — Kingdom Animalia · medium · theory
Higher animals show an elaborate sensory and neuromotor control, which is largely absent in:
A. Other animals
B. Plants (they lack a nervous system) ✓ Correct
C. Vertebrates
D. Mammals
Solution: A defining animal feature is a nervous/neuromotor system enabling rapid responses — plants lack this.
Q5 — Kingdom Animalia · medium · theory
Which characteristic clearly distinguishes Animalia from Plantae AND Fungi together?
A. Being eukaryotic
B. Absence of a cell wall ✓ Correct
C. Presence of a nucleus
D. Multicellularity
Solution: Both plants and fungi have cell walls (cellulose/chitin); animal cells lack a cell wall — a clean distinguishing trait.
Q6 — Kingdom Animalia · medium · theory
Sexual reproduction in most animals is characterised by:
A. Only asexual budding
B. Alternation of generations with a dominant gametophyte
C. Spore formation as the main mode
D. Copulation followed by embryological development ✓ Correct
Solution: Most animals reproduce sexually by copulation, fertilisation and embryonic development.
Q7 — Kingdom Animalia · hard · theory
The key features used to place an organism firmly in Animalia rather than Protista is:
A. Being heterotrophic
B. Having a nucleus
C. Multicellularity with tissue-level (or higher) organisation ✓ Correct
D. Being eukaryotic
Solution: Unicellular heterotrophic eukaryotes are Protista; multicellular heterotrophs with organised tissues are Animalia.
Q8 — Kingdom Animalia · hard · theory
Both animals and fungi are heterotrophic eukaryotes storing glycogen. The fundamental difference lies in:
A. Their DNA
B. Being eukaryotic
C. Mode of nutrition (holozoic ingestion vs absorptive) and absence/presence of a chitin wall ✓ Correct
D. Presence of a nucleus
Solution: Fungi absorb nutrients through chitinous walls; animals ingest food and have no cell wall — hence separate kingdoms.
Q9 — Kingdom Animalia · hard · theory
The presence of a "neuromotor and sensory apparatus" and "muscular movement" are hallmarks that separate Animalia. These arose in evolution with:
A. Autotrophy
B. The presence of chloroplasts
C. The development of true tissues and organs ✓ Correct
D. The chitin cell wall
Solution: True tissues (from Cnidaria upward) enabled nervous coordination and muscular movement, distinctive of most animals.
Q10 — Kingdom Animalia · easy · numerical
A characteristic feature of the cells of Kingdom Animalia is the:
A. presence of a chitinous wall
B. absence of a cell wall ✓ Correct
C. presence of a cellulose wall
D. presence of a large central vacuole
Solution: Animal cells uniquely lack a cell wall; walls of chitin or cellulose belong to fungi and plants respectively.
Q11 — Kingdom Animalia · easy · numerical
Unlike plants and fungi, most members of Kingdom Animalia pass through a distinct:
A. mycelial stage
B. plasmodial stage
C. gametophyte stage
D. embryonic (embryological) stage during development ✓ Correct
Solution: Animals typically develop through embryonic stages after fertilisation, a feature not seen in the plant gametophyte, slime-mould plasmodium or fungal mycelium.
Q12 — Kingdom Animalia · easy · numerical
Which of the following is a phylum belonging to Kingdom Animalia?
A. Chrysophyta
B. Cyanobacteria
C. Arthropoda ✓ Correct
D. Basidiomycetes
Solution: Arthropoda is an animal phylum; Basidiomycetes are fungi, Chrysophyta are protists, and Cyanobacteria are monerans.
Q13 — Kingdom Animalia · medium · numerical
Assertion (A): Animals are heterotrophic and depend directly or indirectly on plants for their food. Reason (R): Animal cells lack chlorophyll and therefore cannot manufacture their own organic food.
A. Both A and R are true and R is the correct explanation of A ✓ Correct
B. Both A and R are true but R is not the correct explanation of A
C. A is true but R is false
D. A is false but R is true
Solution: Because they have no chlorophyll (R), animals cannot photosynthesise and must obtain ready-made food (A) — R correctly explains A.
Q14 — Kingdom Animalia · medium · numerical
Which combination of features taken together is UNIQUE to Kingdom Animalia when compared with Monera, Protista, Fungi and Plantae?
A. multicellular, wall-less cells with holozoic nutrition and nervous coordination ✓ Correct
B. eukaryotic and multicellular cells
C. a cell wall combined with heterotrophic nutrition
D. heterotrophic and eukaryotic cells
Solution: Only animals combine multicellularity, the absence of a cell wall, holozoic (ingestive) nutrition and a nervous system; the other combinations are shared with plants or fungi.
Q15 — Kingdom Animalia · medium · numerical
Which statement about nutrition in Kingdom Animalia is INCORRECT?
A. Ingested food is digested within a body cavity or gut
B. Nutrition among animals may be herbivorous, carnivorous or omnivorous
C. Most animals show holozoic nutrition with internal digestion
D. All animals are holozoic and none of them are parasitic ✓ Correct
Solution: The statement that no animals are parasitic is false — tapeworms, leeches and many others are parasitic; the remaining statements about animal nutrition are correct.
Q16 — Kingdom Animalia · medium · numerical
Assertion (A): Sponges as well as complex higher animals are all placed in Kingdom Animalia. Reason (R): All members of Animalia are multicellular, eukaryotic and lack a cell wall.
A. Both A and R are true and R is the correct explanation of A ✓ Correct
B. A is true but R is false
C. A is false but R is true
D. Both A and R are true but R is not the correct explanation of A
Solution: Sponges and higher animals share the defining animal traits given in R (multicellular, eukaryotic, wall-less), which is why they are grouped together as in A.
Q17 — Kingdom Animalia · medium · theory
Kingdom Animalia are characterized by-
A. Heterotrophic eukaryotic unicellular & multicellular organism that lack cell wall
B. Holozoic, digest food in an internal cavity and store food as complex carbohydrates or fat ✓ Correct
C. All of the above
D. Higher as well as lower forms show elaborate sensory mechanisms
Solution: Animals are holozoic multicellular heterotrophs that digest food internally and store glycogen or fat; only higher forms (not lower) show elaborate sensory/neuromotor mechanisms.
Q18 — Kingdom Animalia · hard · theory
How many of the following terms are correct about Animalia: Heterotroph, eukaryotic, prokaryotic, unicellular, multicellular, store food as glycogen, presence of elaborated neuromotor mechanism without any exception, embryological development?
A. 5 ✓ Correct
B. Less than 3
C. More than 6
D. 6
Solution: Correct: heterotroph, eukaryotic, multicellular, store glycogen, embryological development (5); animals are not prokaryotic/unicellular and neuromotor mechanisms occur only in higher forms.
