Kingdom Animalia Characteristics — NEET Biology
📚 Practice ConceptThis kingdom is characterised by heterotrophic eukaryotic organisms that are multicellular and their cells lack cell walls. They directly or indirectly depend on plants for food. They digest their food in an internal cavity and store food reserves as glycogen or fat. Their mode of nutrition is holozoic – by ingestion of food. They follow a definite growth pattern and grow into adults that have a definite shape and size. Higher forms show elaborate sensory and neuromotor mechanism. Most of them are capable of locomotion.
Assertion (A): Kingdom Animalia consists of heterotrophic eukaryotic organisms that lack cell walls. Reason (R): Animals obtain nutrition through holozoic mode by ingestion of food.
View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
Both statements are exact NCERT quotes. NCERT states “This kingdom is characterised by heterotrophic eukaryotic organisms that are multicellular and their cells lack cell walls” (Assertion true) and “Their mode of nutrition is holozoic – by ingestion of food” (Reason true). The Reason explains HOW the lack of cell walls mentioned in the Assertion enables the holozoic nutrition method.
