The correct answer is:
syngamy, triple fusion
Double Fertilization:
- Pollen tube releases the two male gametes into the cytoplasm of the synergid.
Male gamete 1 (n) + Egg cell (n) --------(Syngamy)-------- Zygote (2n)
Male gamete 2 (n) + Central cell (2n) ------(Triple Fusion)----- Primary endosperm cell (PEC)(3n) (two nuclei of n each)
- Syngamy + Triple fusion = Double fertilization.
