Practice question

Practical or utilitarian classification arranges plants according to economic uses and human utility food cereals pulses vegetables, fiber cotton jute, timber teak sal, medicinal alkaloid sources, ornamental landscaping rather than morphology or phylogeny. It groups wheat with rice as cereals despite similar floral reduction, legumes together regardless of floral structure reflecting functional usage. Morphology basis natural classification, phylogeny phylogenetic, cytology cytotaxonomy chromosome based. Practical classification prevalent in agriculture, forestry, pharmacognosy for inventory and commerce management, not scientific systematics. Advantage lies in resource economics but creates artificial heterogenous groups encompassing unrelated families coincidentally sharing utilitarian property.
