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:

In a fertilized embryo sac, unused cells like synergids and antipodals degenerate, while the zygote and PEN develop further.

Answer 1

The Correct Option is B

Identifying the labeled parts of the fertilized embryo sac. 
- A represents degenerating synergids, which are no longer functional after fertilization. 
- B is the zygote, formed by the fusion of male and female gametes. 
- C is the Primary Endosperm Nucleus (PEN), which develops into endosperm to nourish the embryo. 
- D represents degenerating antipodal cells, which have no role post-fertilization.
