Which of the following plant pairs have bisexual flowers?a)Hibiscus an...
The correct answer is Hibiscus and Mustard.
- Hibiscus 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.
- 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.

Understanding Bisexual Flowers
In botany, bisexual flowers, also known as perfect flowers, contain both male (stamens) and female (pistils) reproductive organs. This allows them to self-pollinate or cross-pollinate, enhancing their reproductive efficiency.
Plant Pairs Analysis
- Hibiscus:
- Hibiscus flowers are known for having both stamens and pistils.
- They possess a prominent style and stigma, indicating their ability to produce seeds after pollination.
- Mustard:
- Mustard plants also feature bisexual flowers.
- Each flower has a complete set of reproductive organs, allowing for both self-fertilization and cross-pollination.
- Watermelon:
- Watermelon plants produce unisexual flowers.
- Male flowers only have stamens, while female flowers contain pistils, making them incapable of self-pollination.
- Papaya:
- Papaya plants exhibit a similar pattern.
- They can have male, female, or hermaphroditic flowers, but the commonly cultivated varieties are often dioecious, meaning they have distinct male and female plants.
Conclusion
Given this analysis, the correct answer is indeed option 'A' (Hibiscus and Mustard) as both plants exhibit bisexual flowers. Watermelon and Papaya do not possess this characteristic, as they either have unisexual flowers or a mix of flower types.
Understanding the flower structures is crucial for horticulturists and botanists as it influences pollination strategies and crop yields.
