Um...well im not really sure about this one but a google defintion explains it well here it is:The pollen tube enters the ovule through the micropyle and ruptures. One sperm cell fuses with the egg forming the diploid zygote. The other sperm cell fuses with the polar nuclei forming the endosperm nucleus. Most angiosperms have two polar nuclei so the endosperm is triploid (3n).
