Answer:
Structure of a Mature Embryo Sac: A mature embryo sac is a 7-celled structure and has 8 nuclei. The end near the micropyle is called the micropylar end while the opposite end is called the chalazal end. Following are the main parts of the embryo sac:
Egg Apparatus: The egg apparatus is composed of two synergids and an egg. There are special thickenings at the micropylar end of synergids. These thickenings are called filiform apparatus.
Function of Synergids: The synergids provide a channel for the pollen tube to enter through filiform apparatus.
Polar Nuclei: The two nuclei enclosed in the central cell are called polar nuclei.
Antipodals: The three cells at the chalazal end are called antipodals.
