NEET · Biology · STD 12 - 1. sexual reproduction in flowering plants
In angiosperm, the haploid, diploid and triploid structures of a fertilized embryo sac sequentially are :
- A Synergids, antipodals and Polar nuclei
- B Synergids, Primary endosperm nucleus and zygote
- C Antipodals, synergids, and primary endosperm nucleus
- D Synergids, Zygote and Primary endosperm nucleus
Answer & Solution
Correct Answer
(D) Synergids, Zygote and Primary endosperm nucleus
Step-by-step Solution
Detailed explanation
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.
