In a double-replacement reaction, two reactants exchange ions to form two products. Therefore, there are two reactants and two products in this type of reaction.
In double fertilization, a zygote and endosperm are formed. The zygote develops into the embryo, while the endosperm provides nutrition to the developing embryo in flowering plants.
In a double replacement reaction, there are typically 2 reactants and 2 products formed. This reaction involves the exchange of ions between two compounds, resulting in the formation of two new compounds.
Double fertilization + syngamy occurring in angiosperms is called triple fusion.
Double Displacement (sometimes called Double Replacement)
What are the two distint fertilization that happen in endosperm
The Generative nucleus arrives at the embryo sac inside the ovule and undergoes division to produce two haploid male nuclei. One of the male nuclei fuses with the haploid female gamete nucleus and for a diploid zygote. The other Male nuclei fuses with 2 polar female gametes to produce the triploid nucleus. This is known as the endosperm nucleus and it acts as a food source for developing zygote.
A triploid cell resulting from double fertilization becomes the endosperm, which provides nutrients to the developing embryo in plants.
