The tube contains two sperm cells that are delivered to the ovary. In fertilization, a sperm cell fuses with an egg to become the embryo of the seed. The second sperm cell fuses with two other cells to he come the endosperm, which feeds the embryo. This "double fertilization" means that the seed will have plenty of food and can mature quickly.
