AMUAMU 1997
Solution:
: In a mature fertilized angiosperm ovule, endosperm is 3n which is formed by the fusion of one of the sperm cell (n) with the two polar nuclei (2n); egg is 2n as the other sperm cell fuses with the egg (female gamete, n) during fertilization to form the zygote (2n). Antipodal cells are haploid (n) which lie at the chalazal end of the embryo sac. In a typical angiospermic embryo sac, there are 3 antipodals.
