NEET (UG) 2023 — Question 101
In angiosperm, the haploid, diploid and triploid structures of a fertilized embryo sac sequentially are :
- Option A:
Antipodals, synergids, and primary endosperm nucleus
- Option B:Correct
Synergids, Zygote and Primary endosperm nucleus
- Option C:
Synergids, antipodals and Polar nuclei
- Option D:
Synergids, Primary endosperm nucleus and zygote
Answer: B
Step-by-step solution
Synergids are the cells of gametophyte and hence these are haploid Zygote is formed by fusion
of two gametes and thus it is diploid. Primary endosperm nucleus is formed by the fusion of
diploid secondary nucleus with a male gamete. Therefore, it is triploid.
