What is the difference between double fertilization and triple fusion?
Asked by YASHASVI NARULA | 19 Jan, 2012, 09:27: PM
Expert Answer
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.
Triple fusion --> Here, the haploid male gamete fuses with the secondary nucleus (diploid) to form the triploid endosperm nucleus, which later forms the endosperm.
Syngamy --> Here a male gamete fuses with a female gamete(egg) in order to give rise to zygote.
So triple fusion is a part of double fertilization.
