Practice question

Taxonomy sensu stricto encompasses three interrelated core tasks alpha taxonomy: identification determination of unknown specimen using analytical keys and comparison, nomenclature provision of correct scientific names following ICBN ICZN codes of rules, and classification hierarchical arrangement into taxa based on relationships. Physiology study of functional processes metabolism photosynthesis belongs to plant physiology, not central taxonomic practice even though physiological characters like C3 C4 may supplement classification. Inclusion of physiology as key aspect confuses systematics with organismal biology. Modern polyphasic taxonomy incorporates multiple evidences but primary pillars remain identification nomenclature classification triad as per de Candolle and contemporary definitions.
