The correct option is (c).
Explanation
Flowers are the reproductive units in angiosperms. Based on the presence of reproductive organs, flowers are classified into two types: bisexual (containing both male and female reproductive structures) and unisexual (containing only one type of reproductive structure).
Statement-wise Analysis
- Statement 1 is Correct: A bisexual flower contains both the androecium (stamens, the male reproductive part) and the gynoecium (pistil/carpel, the female reproductive part) within the same floral structure. Examples include Hibiscus and Mustard.
- Statement 2 is Incorrect:
- Corn (Maize): It produces unisexual flowers. It is a monoecious plant, meaning both male (tassels) and female (cobs) flowers are present on the same plant but are distinct.
- Papaya: It produces unisexual flowers. It is typically a dioecious plant, meaning male and female flowers grow on separate individual plants.
- Statement 3 is Correct: Since bisexual flowers possess both anthers and stigmas in close proximity within the same flower, the transfer of pollen grains from the anther to the stigma of the same flower (autogamy) is physically easier compared to unisexual flowers, which rely on external agents or movement to transfer pollen to a different flower.
Key Takeaway
Bisexual flowers (e.g., Hibiscus, Rose) contain both stamens and pistils. Unisexual flowers lack one of these organs and are found in plants like Corn (monoecious) and Papaya (dioecious).
