Seeds develop from structures called ovules inside the ovary.
In order for the ovule to develop into a seed, a minute 7-celled embryo sac inside must be fertilized by two sperm. One sperm unites with the egg to form an embryo. A second sperm unites with two polar nuclei inside the endosperm mother cell to form the food-storage tissue in a seed called endosperm.
