In flowering plants, following fertilization, the ovule develops into the seed, which contains the embryo and stored food. The ovary, which encloses the ovules, develops into the fruit, protecting the seed(s) and often aiding in their dispersal.
Fertilization triggers the post-fertilization changes in the flower, leading to the development of the fruit from the ovary and the seed(s) from the ovule(s).
The fruit wall is derived from the ovary wall and is called the pericarp. Different parts of the flower, such as the petals, sepals, and stamens, usually wither and fall off after fertilization.
