Where does sugar come from during ripening?

Explanation:
Sugar in ripening fruit mainly comes from the sugars produced by photosynthesis in the leaves and then transported to the fruit through the phloem as a sugar solution. The phloem carries sucrose dissolved in water, delivering it to the developing fruit so it can accumulate sweetness as it ripens. Some starch already stored in the fruit can be converted into sugars during ripening, but the primary source is the phloem-delivered sugars from photosynthesis. Seeds or roots aren’t the direct source of the sugars for ripening.
