(d) An ideal embryo sac contains 7-cells and 8-nuclei. 3-cells are present at the micropylar end and form egg apparatus, mid of which egg cell and rest two lateral form synergids. One cell present in the centre of embryo sac, known as central cell and contains two nuclei and rest three cells are present at chalazal end for antipodal cells. |
