What is the function of the two male gametes produced by each pollen grain in angiosperms?
Answers (1)
In angiosperms, each pollen grain generates two male gametes, which perform the following roles:
Zygote Formation: One male gamete fuses with the egg cell in the embryo sac, creating a diploid zygote that develops into the embryo.
Endosperm Development: The other male gamete combines with the two central polar nuclei in the embryo sac, forming a triploid primary endosperm nucleus (PEN), which gives rise to the endosperm and provides nourishment to the developing embryo.
This unique process is known as double fertilization.
