• The male reproductive parts are the stamens, which produce pollen.
• The female reproductive parts are the pistil, which contains the ovary and stigma.

• Mustard also has both male and female reproductive parts in the same flower. The male reproductive parts are the stamens, which produce pollen. The female reproductive parts are the pistil, which contains the ovary and stigma.
•  Watermelon has male flowers and female flowers and Papaya, on the other hand, has unisexual flowers. This means that male and female reproductive parts are in separate flowers.
• Papaya has separate male and female flowers on the same plant, so the individual flowers are not bisexual.
