gymonecium
The fruit is the ripened ovary of a flower.
The ovary of the flower develops into a fruit.
Once the flower has been polinated, it eventually turns into a fruit. This happens in the female part of the flower.
A starch is actually a long chain of sugar molecules. As the fruit ripens, the starches break apart into the sugar molecules. This is why they become sweeter as they ripen.
