Statement A : Syngamy leads to the formation of zygote. Statement B : Each embryo sac has threecelled egg apparatus –one egg cell and two antipodals, three synergid cells and two polar nuclei.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Each embryo sac has a three-celled egg apparatus –one egg cell and Two synergids , three antipodal cells and two polar nuclei.

In double fertilization
1 Male gamete fuses with diploid secondary nucleus to produce triploid primary endosperm nucleus.
2 Male gamete fuses with egg cell to form zygote
3 Both (1) and (2)
4 Male gamete fuses with egg cell to form zygote only
Explanation:
One of the male gametes fuses with the egg cell (syngamy) to form a zygote. The other male gamete fuses with the diploid secondary nucleus to produce the triploid primary endosperm nucleus (PEN).
