This tiny terminal cell will become the embryo proper. It is pushed into the liquid endosperm region by growth of the suspensor. The suspensor is genetically identical to the embryo proper. The proximal portion of the embryo attached to the suspensor differentiates into a root apex. This stage of development is called the heart stage.
Torpedo means fusiform at one end and with two fin-like projections at the other.
This embryo may elongate enough to need to bend within the confines of the ovule, and its development may use up all available endosperm as well. Thus mature seeds may lack endosperm. This change forces another. The carpel is renamed fruit. As you recall the gymnosperms were noted for their naked seeds.
