Higher Taxonomic Categories & Hierarchy — NEET Biology
📚 Practice ConceptYou have seen earlier that categories like species, genus and families are based on a number of similar characters. Generally, order and other higher taxonomic categories are identified based on the aggregates of characters. Order being a higher category, is the assemblage of families which exhibit a few similar characters. The similar characters are less in number as compared to different genera included in a family. Plant families like Convolvulaceae, Solanaceae are included in the order Polymoniales mainly based on the floral characters. The animal order, Carnivora, includes families like Felidae and Canidae.
Assertion (A): Order Polymoniales is classified primarily using floral characters. Reason (R): Lower taxonomic ranks like family rely more on ecological and geographical distribution than morphology.
View solution & NCERT explanation
Correct answer: C — A is true, but R is false
Family classification uses both vegetative and reproductive features, not geography/ecology alone.
