In angiosperm female gametophyte also called embryosec is an oval multicellular haploid structure embedded in the nucellus at the micropylar end of the ovule .
The most commen type of embryosec in angiosperm is polygonum type .
A typical embryosec is 8 cell and 8 nucleated in immature stage but 7 celled and 8 nucleted in mature stage .
The nuclear arrangement of embryosae is 3+2+3 .
The three mycropylar cells are collectively called egg apparatus containing 2 syneagid and one large egg cell.
The synergid or help cell cointain filiform apparatus showing finger like projection .
The synergid helps in the guidance of the path of pollentube where as egg cell represent the single female gamete of embryosec .
The three chalazal cell of embryosec is called an antipodal cell and they are the vegetative cells of embryosec which may be degenerated .
The central cell is the largest cell of embryosec which cointain two polar nuclei this two polar nucelei soon fuse to form a single diploidsewndary or fusion or definitive nucleus .
Besides thes the embryosec also contain some vacules at the central part .
