In angiosperms, which nuclei fuse during triple fusion?
Answer and explanation
Correct answer: One male gamete and two polar nuclei
Triple fusion occurs when one male gamete fuses with the two polar nuclei in the central cell of the embryo sac. The resulting primary endosperm nucleus is usually triploid and begins endosperm development. The egg-cell fusion is syngamy, while the two polar nuclei may first fuse with each other to form a secondary nucleus but that event alone is not triple fusion.
