Hi...
Pollen tube can enters through 1)chalazal end- chalazogamy.
2)micropylar end - porogamy
3)integuments- mesogamy..
Irrespective of the place of entry it reaches the micropylar end ..due to the presence of synergyds. Syneryds produces chemicals2 which the pollen tube gets attracted....and then thefurther process....
Hope this helps u!!
