Key Points
Key Points: Sexual Reproduction in Plants
- Flower is the main reproductive organ in plants, made up of four whorls—calyx, corolla, androecium, and gynoecium.
- Essential whorls: Androecium (male) and Gynoecium (female);
Accessory whorls: Calyx (sepals) and Corolla (petals). - Bisexual flowers have both androecium and gynoecium (e.g., Hibiscus);
Unisexual flowers have only one (e.g., Papaya). - Gynoecium contains carpels with ovary, style, and stigma;
Ovary has ovules, which form the embryo sac by meiosis.
