Which statement correctly identifies double fertilization in angiosperms?
Answer and explanation
Correct answer: One male gamete fuses with the egg cell, and the other fuses with the secondary nucleus.
Double fertilization is the defining reproductive feature of angiosperms and consists of two fusion events. One male gamete fuses with the egg to form a diploid zygote, called syngamy. The second fuses with the secondary nucleus, producing the primary endosperm nucleus through triple fusion. The other options describe no normal double-fertilisation event.
