Corn and Cucumber
Explanation
Angiosperm flowers are classified based on the presence of reproductive whorls:
- Bisexual (Hermaphrodite) Flowers: Contain both the androecium (stamens/male) and gynoecium (pistil/female) within the same flower.
- Unisexual Flowers: Contain either stamens or pistils, but not both. These flowers are either staminate (male) or pistillate (female).
Analysis of the Plants:
- Corn (Maize): Produces unisexual flowers. It is a monoecious plant, meaning separate male (tassels) and female (ears) flowers are located on the same plant.
- Cucumber: Produces unisexual flowers. It is typically monoecious, bearing separate male and female flowers on the same vine.
- Mustard, Rose, and Petunia: These plants produce bisexual flowers, containing both male and female reproductive organs.
- Papaya: Produces unisexual flowers, but it is typically dioecious (male and female flowers on separate plants). While Papaya fits the unisexual criteria, it is paired with Petunia (bisexual) in Petunia and Papaya.
Therefore, the set where both plants produce unisexual flowers is Corn and Cucumber.
Key Takeaway:
Unisexual flowers are found in plants like Corn, Cucumber, Papaya, and Watermelon. Bisexual flowers are found in plants like Mustard, Rose, Hibiscus, and Petunia.
