→When pollens falls on the stigma of the flower,pollen tube formation takes place due to their germination. →Now 2 male gametes passes through the formed pollen tube and enters to the ovule. →Out of the 2 male gametes, one fuses with egg and other male gamete fuses with the nuclie.
→So,this fertilization involves fusion of 3 haploid cells and hence the process is called as triple fertilization.
