Answered by palashpratik226

Answer:

The pollen tube enters the ovule in majority of cases through micropyle by a process termed porogamy or it may enter through chalaza (chalazogamy) as in Casuarina. In rare cases the pollen tube may pierce through integuments (mesogamy) as in Populus, Cucurbita.
