The main difference between a fruit and vegetable is what part of the plant it comes from.
A fruit is scientifically defined as “the mature ovary of a flowering plant that is edible.” The fruit is the ovary, the seed or seeds it encloses, and any parts associated with the ovary.
There is no precise/scientific definition for vegetable, but the basic definition is “the edible root, tuber, leaf, stem, seed or flower of a plant.” A vegetable is a plant or that part of a plant which is edible, and does not necessarily have a role in the plants reproductive cycle.
