Question

What is double fertilization?

Answer 1

Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm).

Answer 2

double fertilization happens in the flower where it is sexual reproduction n not a asexual reproduction...there are 2 nuclei .one of them fuses with the egg to form a zygote.by the tym the egg cell has been fertilized the two polar nuclei combine to form a single fusion nucleus. now the second sperm deposited in the embryo sac by the pollen tube moves to the center and unites with the fusion nucleus.the zygote will develop into an embroyonic plant within the ovule.union of the fusion nucleus with the second male nucleus stimulates the formation of a new tissue the endosperm.in which food materials are stored as development of the ovule proceeds. union of one nucleus with the egg and the second nucleus with the fusion nucleus is called double fertilization....................
