Answer :

The polar cell contains 2 nuclei.

Double fertilization:

• It is the phenomenon in which when a pollen reaches the stigma of the female flower, it germinates to produce 2 male nuclei and a vegetative cell.

• The 2 male nuclei enters the embryo sac, one of the male gamete fuses with egg to form a diploid zygote & the other male gamete fuses with diploid secondary nucleus to form triploid primary endosperm nucleus (PEN).

• Hence, because of the two fusions this phenomenon is called double fertilization.
