Why is pumpkin flower called uni sexual flower?

Pumpkin flowers are considered unisexual because they produce only one type of reproductive structure: male or female. Male flowers, which have stamens, produce pollen, while female flowers, which contain ovaries, develop into fruit when fertilized. This separation of sexes helps in the efficient pollination process, as typically, both male and female flowers bloom at different times, attracting pollinators to facilitate reproduction.
