Question

Identify the correct labellings in the figure of a fertilised embryo sac of an angiosperm given below:

• A. A – zygote, B – degenerating synergids, C – degenerating antipodals, D – PEN
• B. A – degenerating synergids, B – zygote, C – PEN, D – degenerating antipodals
• C. A – degenerating antipodals, B – PEN, C – degenerating synergids, D – zygote
• D. A – degenerating synergids, B – zygote, C – degenerating antipodals, D – PEN

Hint:

The fertilised embryo sac represents the beginning of seed development, with the zygote developing into the embryo and the PEN forming the endosperm.

Answer 1

The Correct Option is B

In the fertilised embryo sac of an angiosperm: A: Degenerating synergids – Synergids disintegrate post-fertilization. B: Zygote – Originates from the fusion of the male gamete and the egg cell. C: Primary Endosperm Nucleus (PEN) – Formed by the fusion of the secondary male gamete with the two polar nuclei. D: Degenerating antipodals – Antipodals disintegrate post-fertilization.
