Identify the FOUR successive whorls of a typical flower from outside to inside.
AAndroecium → Gynoecium → Calyx → Corolla
BCalyx → Corolla → Androecium → Gynoecium (calyx outermost, gynoecium innermost on the thalamus)
CCorolla → Calyx → Gynoecium → Androecium
DGynoecium → Androecium → Corolla → Calyx
Answer & Solution
Correct answer: B. Calyx → Corolla → Androecium → Gynoecium (calyx outermost, gynoecium innermost on the thalamus)
Outermost to innermost: Calyx (sepals, protective) → Corolla (petals, often coloured for attraction) → Androecium (stamens, male) → Gynoecium (carpels, female). Calyx + Corolla are 'accessory'; Androecium + Gynoecium are reproductive.
