What is triple fusion? Where and how does it take place? Name the nuclei involved in triple fusion.
Triple fusion is the fusion of the male gamete with polar nuclei in the embryo sac of the angiosperm. This manner of fusion takes area in the embryo sac. When pollen grains fall at the stigma, they germinate and deliver upward push to the pollen tube that passes thru the style and enters into the ovule. After this, the pollen tube enters certainly considered one among synergids and releases male gametes there. Out of the 2 male gametes, one gamete fuses with the nucleus of the egg mobileular and paperwork the zygote (syngamy). The different male gamete fuses with the 2 polar nuclei gift withinside the important mobileular to shape a triploid number one endosperm nucleus. Since this technique includes the fusion of 3 haploid nuclei, it's far called triple fusion. It consequences withinside the formation of the endosperm. One male gamete nucleus and polar nuclei are concerned on this method.
