Question

Where is the part that will develop into a fruit on a male flower?

Answer 1

Actually, flowers haven't genders, like " woow, that's a male flower". WROOONG. Flowers have, indeed, parts of themselves that are their male reproductive system and their female reproductive system. Butt* the part of the flower that develop, as you said, into a fruit it's the ovary, after being pollinated by pollen from the anther of another flower (ovary is the female part of the flower and the anthers are the male part)

*that's a joke, ok?
