Options

  1. AFusion of two male gametes with one egg
  2. BFusion of one male gamete with two polar nuclei
  3. CFusion of two male gametes for pollen tube with two different eggs
  4. DSyngamy and triple fusion

Correct answer

D. Syngamy and triple fusion

Step-by-step solution

Double fertilization is a phenomenon unique to angiosperms. Each pollen grain produces two sperm; Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote (syngamy); the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm (triple fusion) Together, these two fertilization events in angiosperms are known as double fertilization.
