What is triple fertilization? |
| Answer» Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation. ... One of the two male gametes fuses with the nucleus of the egg cell to produce the zygote, this process is referred to as syngamy.\xa0Triple fusion\xa0is defined as\xa0fusion taking place\xa0between two polar nuclei and sperm nucleus. This happens during double fertilization in a seed plant, and therefore gives origin to a triploid nucleus known as the Primary Endosperm Nucleus(PEN). The PEN later evolves into an endosperm. | |
