Question

what is double fertilization in flowering plants​

Answer 1

Explanation:

1. Double Fertilization. ... Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm. Together, these two fertilizationevents in angiosperms are known as double fertilization.
2. Double fertilization is a complex fertilizationmechanism 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

Answer:

double fertilisation =syngamy +tripule fusion is called double fertisation

Explanation:

double fertilsation occurs in flowering plants the pollen grain enter through the female gametophyte(egg cell) in egg cell . the upper there are three antipodals and middle two polar nuclei ,central cell and egg cell and at the base 3 three synergids are present in which the filiform apparetus (guide the entry of the male gametophyte) the male gametophyte enters into female gamatophyte by three events they are chalazal end(in which the pollen tube enters by anterior end) and micropylar end(in whichtriple f the pollen tube enter by posterior part) andngamy anatropus (in which enters into middle end). than the pollen if enter through chalazal end it will e guide by the filiform apparatus of synergies and enters into female gamatophyte after the bursting of pollen tube the male gamatophyte releases two nuclei in which the it binds with the one nuclei bind with polar nuclei of female gametophyte so it is called triple fusion and the other nuclei of male gametophyte binds with egg cell so it is called syngamy so the double fertilasation =triple fusion +syngamy . so it the brief account of double fertilisation .hope it helps you☺
