antipodal cells

antipodal cells

the three haploid cells that remain at the non-micropylar end of the EMBRYO SAC subsequent to division of the cells. After the formation of the egg cell they play little or no further part in seed development.

The mature embryo sac is composed of 7 cells, one central cell contained polar nuclei or secondary nucleus, two synergids and one egg cell that formed egg apparatus and three antipodal cells that are degenerate in the mature embryo sac before fertilization.
Based on present embryological studies, many exceptional events were reported in the members of this family, including Nemec phenomenon (Davis, 1968; Batygina, 1987), increasing of synergids (Cichan and Palser, 1982), increasing of antipodal cells (Richards, 1997; Pandey, 2001), four-celled female gametophyte (Harling, 1951) and apomixis (Davis, 1968; Chaudhury et al.
