2.3 Dotble Fertilisation Atter entering one of the synergids, the pollen tube releases the yndesperve food materials and at gametes into the cytoplasm of the synergid. One of the thete the developing embryo. in moves towards the egg cell and fuses with its nucleus thus cotrone endosperm development, the syngamy. This results in the formation of a diploid cell, the mose exictear divistons to give ris other male gamete moves towards the two polar nuclet located in the endosperm development is cell and fuses with them to produce a triploid primary endospem thes sibsequently cell wall (PEN) (Figure 2.13a). As this involves the fusion of three haplasenendosperm becomes cellu is termed triple fusion. Since two types of fusions, synganny ast wates from tender cocon fusion take place in an embryo sac the phenomenon is termed brnothing but free-nuc fertilisation, an event unique to flowering plants. The central oul thousands of nuclell ant triple fusion becomes the primary endosperm cell (PEC) and ditithe celtular endosperm into the endosperm while the zygote develops into an embrya. developing embryo (e.g. maturation or it may $p$ and eoconut) and be $u$ open some seeds of $c$ coconut and look for whether the endospt and maize.
