Question

why does Hibiscus not bears fruit even though androecium and gynoecium present in it

Answer 1

Hibiscus is a plant that does not produce any fruit or you can say that the fruit is hidden. The fruit of the hibiscus flower is the five lobed pod or capsule just below the flower. The lobs of pods contain seeds like any other fruit. So, the hibiscus plant does not have any distinct fruit.
