Answer:
unisexual flowers
The flowers which contain either only the pistil or only the stamens are called unisexual flowers. The flowers which contain both stamens and pistil are called bisexual flowers. Corn, papaya and cucumber produce unisexual flowers, whereas mustard, rose and petunia have bisexual flowers.
Explanation:
Flowers are nature's way of ensuring that the plant will reproduce via seeds and carry on its genetic makeup. Many flowers contain both male and female parts, called the stamen and the pistil. Some flowers, however, contain only male or female parts and need the help of another flower to form seeds.
Structure. As a plant's reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ.
