Question

Explain double fertilisation or triple fusion

Answer 1

In angiosperms, double fertilisation refers to the fusion of one sperm cell with an egg (syngamy), and another sperm cell with the polar nuclei to yield a triploid endosperm (triple fusion). Double fertilisation involves two processes, triple fusion and syngamy. ... So triple fusion is a part of double fertilization.

Answer 2

1.Definition

Double Fertilization: The fertilization process of angiosperms is called the double fertilization.

Triple Fusion: Triple fusion is the fertilization of two polar nuclei in the embryo sac with a single sperm cell.

2.Correspondence

Double Fertilization: Double fertilization is the fusion of embryo sac with two sperm cells.

Triple Fusion: Triple fusion is one of the two fertilizations of double fertilization.

3.Result

Double Fertilization: Double fertilization forms a diploid zygote, which is developed into the embryo along with the endosperm.

Triple Fusion: Triple fusion forms the endosperm.

4.Ploidy

Double Fertilization: Double fertilization produces a diploid zygote as well as the triploid endosperm.

Triple Fusion: Triple fusion produces the triploid endosperm.
