When a male gamete fuses with two polar nuclei it forms a cell?

The most characteristic feature of angiosperm is double fertilization where one of the male gamete fuses with the egg cell to form zygote and the other male gamete fuses with the two polar nuclei to form the triploid endosperm,after fertilization the ovules ripen into seeds and ovaries ripens into fruits.

What does the fusion of the polar nuclei and sperm form and how many n is it?

Endosperm is formed by the fusion of a haploid sperm (n) with two haploid polar nuclei (n + n) resulting in triplolid endosperm cells (n + n + n = 3n).

What is called double fertilization?

: fertilization characteristic of seed plants in which one sperm nucleus fuses with the egg nucleus to form an embryo and another fuses with polar nuclei to form endosperm.

What is triple fusion?

: the fusion involving two polar nuclei and a sperm nucleus that occurs in double fertilization in a seed plant and results in the formation of the endosperm.
