Question

Double fertilization in angiosperms involves

• A. One male gamete and two female gametes
• B. One female gamete and two male gametes
• C. One male gamete and one female gamete
• D. One male gamete, one female gamete and one vegetative cell

Answer 1

The correct option is B One female gamete and two male gametes

The pollen tube is guided by the chemicals secreted by the synergids present in the embryo sac, and it enters the ovule sac through the micropyle. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm. Together, these two fertilization events in angiosperms are known as double fertilization.
So, the correct answer is 'One female gamete and two male gametes'.
