Name all the haploid cells present in an unfertilised mature embryo sac of a flowering plant. Write the total number of cells in it.

Text Solution

Verified by Experts

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