Question

Define triple fusion. What is the product of this process? What does the product develop into?

Answer 1

Triple fusion in angiosperms is the process where one male gamete fuses with two polar nuclei, forming a triploid triple fusion nucleus called the primary endosperm nucleus. This nucleus develops into the endosperm, which nourishes the developing embryo. Meanwhile, the other male gamete fuses with the egg to form a diploid zygote that develops into the embryo. Thus, triple fusion results in the formation of the primary endosperm nucleus, which ultimately forms the nutritive endosperm tissue in the seed.
