Peter and Naama,

I see. For the events that precede double fertilization, there are several 
terms in GO, I pulled out some of them; Naama please take a look in GO 
process ontology for more:

pollen germination  GO:0009846
Def: The physiological and developmental changes that occur in a 
heterosporous plant pollen grain, beginning with hydration and terminating 
with the emergence of the pollen tube through the aperture.

pollen tube guidance  GO:0010183
Def: The process by which the growth of pollen tube is directed towards 
the female gametophyte.

pollen tube growth  GO:0009860
Growth of pollen via tip extension of the intine wall.
