●Unisexual flowers are the flowers in which either androecium or gynoecium are present. Example- Papaya, Date palm

2. ●Androecium is the whorl of male sexual organ of plants called stamens. Stamens have a stalk called Filament and a bilobed structure known as anther.

●Gynoecium is the whorl of female sexual organ of plants called pidtils. Pistils have 3 parts named Stigma, style and Ovary.
