Question

Give the names of structured which has diploid ploidy in embryo sac after fertilisation

Answer 1

Dear Student, When pollen fertilizes the embryo sac, one pollen fertilizes the egg to form diploid zygote (syngamy) while other pollen fertilizes the polar nuclei(2n) present in embryo sac to form endosperm having triploid ploidy (Triple fusion). This is known as double fertilization. So, the diploid structure present in embryo sac after fertilization is the Zygote. Regards
