The essential whorls of the flower are the
- Calyx and Corolla
- Stamen and ovary
- Calyx and epicalyx
- Androecium and gynoecium
Answer
Androecium and gynoecium
Reason — The essential whorls of the flower are those that are directly concerned with reproduction. Androecium and gynoecium are the male and female reproductive parts of the flower, respectively.
Calyx and Corolla are accessory (non-essential) whorls. Stamen and ovary are parts of the essential whorls, not the whorls themselves. Epicalyx are non-essential structures.
