After the pollen tube enters a synergid, what does it release into the embryo sac?

पर्याय

• Two female gametes

• Two male gametes

• One male gamete and one female gamete

• Three male gametes and one female gamete

Answer 1

After the pollen tube enters a synergid in the embryo sac, it releases two male gametes. These two male gametes are essential for double fertilization: one participates in syngamy with the egg cell, and the second participates in triple fusion with the two polar nuclei.
