Detailed explanation-1: -Final answer: Synergid, zygote and primary endosperm nucleus .
Detailed explanation-2: -The embryo sac has a Haploid ploidy. Haploid cells are usually formed for reproductive purposes. When generating a zygote, distinct copies of the genome can be reorganized by reducing the genome to one copy.
Detailed explanation-3: -In a fertilized embryo sac the haploid, diploid and triploid structures are synergid, zygote and primary endosperm respectively.
Detailed explanation-4: -Embryo sac consists of three parts namely egg apparatus, secondary nucleus and antipodal. Antipodal in turn consists of three cells called haploids. Embryo sac carries two haploid nuclei and six haploid cells that do not have any cell walls.
Detailed explanation-5: -Solution: In a fertilized embryo sac, the haploid structure is the synergids, the diploid structure is the zygote and the triploid structure is the primary endosperm nucleus.
