Pollen tube entry into the synergid cell of Arabidopsis is observed at a site distinct from the filiform apparatus.

Abstract excerpt

In higher plants, the double-fertilization process begins with the successful delivery of two sperm cells to the female gametophyte. The sperms cells are carried by a pollen tube that upon arrival at the micropylar end of the female gametophyte, bursts, and discharges its content into one of two specialized cells called the synergid cells. At their micropylar ends, both synergid cells form a thickened cell wall...
