Two fertilization events take place in angiosperms, producing a zygote and endosperm.

Angiosperms are the only plants to produce seeds after fertilization takes place.

Explanation:
Detailed explanation-1: -This is called double fertilization because the true fertilization (fusion of a sperm with an egg) is accompanied by another fusion process (that of a sperm with the polar nuclei) that resembles fertilization. Double fertilization of this type is unique to angiosperms.
Detailed explanation-2: -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.
