8-nucleate embryo sac is

Solution (By Examveda Team)

The 8-nucleate embryo sac is Monosporic, Bisporic and Tetrasporic.
In flowering plants, double fertilization occurs, which involves two sperm fertilizing the two gametes inside the megagametophyte (the egg cell and the central cell) to produce the embryo and the endosperm.
Bisporic embryo sacs contain nuclei derived from two members of a megaspore tetrad whereas tetrasporic embryo sacs contain nuclei derived from all four members of a tetrad.
