Question 4
In guava, rose apple, brinjal and mangosteen, part of what you eat was never the ovary at all. Which floral part is it?
The right answer is the one marked above.
The sepals. In these flowers they do not fall after fertilisation. They become fleshy and remain fused with the pericarp.
Generally the sepals, petals, stamens and stigma all fall away once fertilisation is done — their work of protecting and advertising is finished. These four plants are the exception, and only the calyx stays.
