(B) The cell of suspensor present at the chalazal end and formed during embryogenesis. (C) The cell of suspensor present at the micropylar end and formed during the formation of the endosperm. (D) The cell of suspensor present at the chalazal end and formed during the formation of the endosperm.

Zygote of an angiospermic embryo divides first to form two cells. One towards the micropyle is called basal cell and the other towards the chalazal end is called embryonal cell. The basal cell divides by transverse divisions to form a 6-10 celled long filament-like structure called suspensor. The main function of suspensor is to push the developing embryo into food laden endosperm to provide nutrition. The micropylar cell of the suspensor swells up and is known as haustorial-cell.
