Detailed explanation-1: -Double fertilization is the characteristic of angiosperms. In this process, one male gamete fuses with the egg to form a zygote, which is known as syngamy. The other male gamete fuses with the two polar nuclei in the central cell to produce a triploid primary endosperm nucleus or PEN.

Detailed explanation-2: -Double fertilization is the process in which a diploid zygote and a triploid endosperm are formed. It is a characteristic found only in angiosperms. In this type of fertilization in which the zygote and endosperm nucleus are formed.

Detailed explanation-3: -Double fertilization is a unique characteristic of angiosperms.

Detailed explanation-4: -The process of double fertilization kickstarts seed formation in flowering plants (angiosperms) by fusing two male gametes (sperm cells) with two female gametes (egg and central cell) to generate the precursor cells for the embryo and endosperm, respectively.

Detailed explanation-5: -Double fertilization is a key event in the lifecycle of angiosperms, but is completely absent in gymnosperms.
