The three cells grouped at the micropylar end of the embryo sac form the:

Answer: Egg apparatus.

  • A Antipodal cells
  • B Egg apparatus
  • C Central cell
  • D Synergid pair only

Correct answer: B. Egg apparatus

Explanation: The egg apparatus consists of two synergids and one egg cell located at the micropylar end of the embryo sac.

Double fertilization: pollen tube delivering two male gametes to the embryo sac, forming zygote and endosperm

Double fertilisation in angiosperms: one male gamete fuses with the egg to form the diploid zygote (syngamy), while the second fuses with the two polar nuclei to form the triploid primary endosperm nucleus (triple fusion). Image: Triploid, CC BY 3.0, via Wikimedia Commons.
