Sexual Reproduction In Flowering Plants Question 1
Question: In angiosperm, the haploid, diploid and triploid structures of a fertilized embryo sac sequentially are :
(1) Synergids, Primary endosperm nucleus and zygote
(2) Antipodals, synergids, and primary endosperm nucleus
(3) Synergids, Zygote and Primary endosperm nucleus
(4) Synergids, antipodals and Polar nuclei
Show Answer
Answer: (3) Synergids, Zygote and Primary endosperm nucleus
Explanation-
Here’s the explanation:
- Synergids are haploid (n).
- The zygote is diploid (2n) as it is formed by the fusion of a haploid sperm cell with a haploid egg cell.
- The primary endosperm nucleus is triploid (3n) as it is formed by the fusion of a haploid sperm cell with two haploid polar nuclei.
