Question

In a fertilized embryo sac, the haploid, diploid and triploid structures are ______.

विकल्प

• antipodal, zygote and primary endosperm nucleus

• synergid, antipodal and egg

• antipodal, polar nuclei and synergid

• synergid, polar nuclei and zygote

Answer 1

In a fertilized embryo sac, the haploid, diploid and triploid structures are antipodal, zygote and primary endosperm nucleus.

Explanation:

In the fertilized embryo sac, the antipodal cells are haploid, the zygote formed by the fusion of the egg and male gamete is diploid, and the primary endosperm nucleus formed by the fusion of the male gamete with two polar nuclei is triploid. This explains the haploid, diploid, and triploid structures, respectively.
