Q. What does filiform apparatus do at the entrance into ovule ?

AIPMTAIPMT 2008Sexual Reproduction in Flowering Plants

Solution:

Filiform apparatus is a prolongation of the synergids beyond the summit of the embryo sac. It helps in guiding the entry of pollen tube into the synergids. Schacht first described this as 'fertilization threads'.
