In angiosperms, the process of seed development begins with double fertilization, which involves the fusion of two male gametes with the egg cell and the central cell to form the primary endosperm and the zygote right after fertilization, the zygote is mostly inactive, but the primary endosperm divides rapidly to form the endosperm tissue. The development of the fruit from flower starts from the stage of fertilization and continues which is described as below: flowers are the true reproductive organs of flowering plants.
