Fertilization in angiosperms involves triple fusion: 1) One sperm cell fuses with the egg cell nucleus, forming a zygote. 2) The other sperm cell fuses with the two polar nuclei in the embryo sac, forming the primary endosperm nucleus. 3) Together, these processes - the fusion of sperm and egg nuclei, and sperm and polar nuclei - are known as triple fusion and allow for the development of the embryo and endosperm tissues following fertilization.

2. what is Flower ?

3.  A Modified Shoot system
 Sexual Reproductive organ of the Plant

4. A FLOWER

5. Fertilization
 Fusion of male and female gamete
 Before fertilization
 In Angiosperm pollen grain dusted on stigma
 Pollen tube formation [ Pollen tube enter into ovule ,
, Fertilization is 3 types ]
Sperms releases into Embryosac
To form the ZYGOTE

6.  Both Sperms fertilize
 The two compartment of Embryosac
 The phenomenon is Double fertilization

7. Syngamy
One of the sperm fuse with egg nucleus

9. Triple Fusion
 Other sperm fuse with Polar nuclei to form the PEN
{ Primary Endosperm Nucleus }
