Question

In a plant, one flower has all the 4 whorls intact, the other flower has shed the androecium and the corolla. What does this imply?

• A. Both flowers are fertilised
• B. The intact flower is fertilised and the other has not been fertilised.
• C. The intact flower is not fertilised and the other has been fertilised.
• D. Both flowers are unisexual

Answer 1

The correct option is C

The intact flower is not fertilised and the other has been fertilised.

There are two flowers in the plant. One flower has all the whorls intact which imply that the plant is bisexual. The shedding off of androecium and corolla implies that the flower has been pollinated and fertilised. After fertilisation, the flower sheds the androecium and the corolla. The role of the corolla of attracting pollinators and the role of the androecium to provide the pollen grains for fertilisation are completed.
