An unfertilised embryo sac of angiosperm is composed of 8-nuclei and 7 cells. Among 8 nuclei, 6 are enclosed by cell walls and organised into cell, while the remaining 2 nuclei (called polar nuclei) are situated above the egg apparatus. Out of 6 cells, 3 are grouped at micropylar end and constitute the egg apparatus, made up of 2 synergids and 1 egg cell. The other 3 are located at chalazal end and are called antipodals.
