The pollen tube usually enters the embryo sac

through one of the synergids

by directly penetrating the egg

between one synergid and central cell

by knocking off the antipodal cells.

Solution

through one of the synergids

The pollen tube arrives in the micropyle of the integument of the ovule, and enters the embryo sac.

The synergids of the embryo sac literally put their energies together to burst the end of the pollen tube. Meanwhile, the generative cell has followed the pathway digested by the tube cell. Along the way it has divided to produce two sperm cells. The two sperm cells exit the pollen tube through the burst end.

One sperm cell unites with the egg. This process is called syngamy (union of gametes) or [gag] fertilization. I much prefer syngamy to fertilization (see below). The product of the union of egg and sperm is called a zygote, and it has two sets of master plans, one from each gamete. The zygote will divide and grow and differentiate to become a new embryonic plant with root, stem, and leaf. Ultimately it will become an adult plant.
