CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)
The correct answer is
Anatomical characters of plants

APG IV Classification: Anatomical Basis Focus

The Angiosperm Phylogeny Group IV (APG IV) system represents a modern approach to plant classification, specifically focusing on flowering plants (angiosperms). This system relies on specific characteristics to group plants according to their evolutionary relationships.

Evaluating Classification Criteria

The question asks for the basis of the APG IV system among the given options:

  • Morphological characteristics of plants
  • Anatomical characters of plants
  • Molecular characteristics
  • Cytological and chemical characteristics

Basis of APG IV System

Based on the provided options and answer, the APG IV system is identified as being based on anatomical characters of plants. This means that the internal structure and organization of plant tissues and organs are considered key features for classification within this system.

While modern classification systems like APG IV heavily utilize molecular data (DNA sequences), this specific question emphasizes anatomical features as the primary basis among the choices presented.
