Embryo Development in Plants: Embryogenesis in Plants

The synergid that the cells were released into degenerates and one sperm makes its way to fertilise the egg cell, producing a diploid (2n) zygote. The second sperm cell fuses with both central cell nuclei, producing a triploid (3n) cell. As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as theThe swellings that develop into cotyledons are located at the end of the embryo on top of the row of single cells.
