What is meant by characterization in the basic steps of taxonomy?

Correct answer: Systematically recording the external and internal traits of an organism

Correct answer: A. Characterization is the careful description of an organism’s observable and studied features. A taxonomist may record external morphology, such as shape, colour, size, leaves, flowers, or body parts, and internal or anatomical features when relevant. These observations provide evidence for comparing the organism with known groups and deciding its identity and relationships. Characterization is therefore an information-gathering step that comes before final identification and naming, although the complete taxonomic process contains several connected steps. B is incorrect because naming is nomenclature, not characterization. C and D are unrelated and are not steps of taxonomy. A useful sequence is characterization, identification, classification, and nomenclature, though practical work may move between some steps. Memory cue: “Characterization asks: what features does it have?”
