Explaination:
As the pollen reached the stigma there is dialogue communication take place whether the pollen reach is right or wrong.
If the pollen fall on stigma is right then they continue continue to grow their pollen tube.
These pollen tube finally enter the ovule with the help of synergids.These are the cells that guides the pollen tube for entry into ovules.
