Why is fruit present in the roots of some plants although it is made in leaves?

Fruit is produced in the ovaries of flowers after fertilization, not directly in the leaves. While photosynthesis occurs in the leaves, the carbohydrates and nutrients synthesized there are transported through the plant to support fruit development in the roots or other parts. Some plants may store energy or nutrients in their roots, leading to the development of fleshy fruits or structures that can utilize these resources for growth and reproduction. This adaptation allows for efficient energy storage and utilization during the fruiting process.
