Flower Structure and Angiosperm Parts — NEET Biology

Correct answer: D — I, II, III, IV, V, VI, VII

The semi-technical description of a flowering plant follows a specific sequence. As per NCERT, the description begins with the plant's habit, followed by vegetative characters (roots, stem, leaves). After that, floral characters are described, starting with the inflorescence, then individual flower parts (calyx, corolla, androecium, gynoecium). Finally, a floral diagram and floral formula are presented. Therefore, the correct sequence is: I. Description of the plant's habit II. Characterisation of vegetative parts (roots, stem, leaves) III. Detailing the inflorescence type IV. Describing the calyx and corolla V. Explaining androecium and gynoecium features VI. Constructing the floral diagram VII. Writing the floral formula Option D correctly lists all steps in the sequence prescribed by NCERT. Options B, C, and A present incorrect permutations of these steps, deviating from the prescribed order of describing vegetative, then floral, then diagrammatic/formulaic aspects.
