Answer 2

Answer:

1) There is formation of a diploid zygote and it develops into an embryo, which forms the future plant. 2) The endosperm cells serve as a source of nutrition for the developing embryo. 5) In most of the plants the antipodals and synergids disintegrate before, during or immediately after fertilization.
