1.Sexual Reproduction in Flowering Plants
medium
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
(NEET-2023)
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.
